This is tower defense offline strategy game for players who love challenging defence and td games. Play this tower defence game now and you will definitely like it.
This is a tower defense with no unique solution. This is a tower defense where you have to try and embrace new strategies. 

Concept is simple: You have waves of multiple incoming "enemies" that must be defended against. Overall whether you will succeed or not will depend on your ability to strategically place and construct towers in the path of attacking enemies. In this strategy game player has a space base that must be defended by the player. You have waves of multiple incoming "enemies" that must be defended against. Overall whether you will succeed or not will depend on your ability to strategically place and construct towers in the path of attacking enemies. 
You have basic towers and tons of (over 60) modules to insert and modify tower performance. Defense of a core from aliens, humanoids and highly intelligent predators not easy that is why the game is built so you will have to adapt to new level constantly. In this TD game you can build anything with our system. YOU can build towers that can cast poison, freeze, confuse enemies, stun, turn them around, weaken them. And moreover you will have to try it like in some other TD games, the game is built so there is no ultimate strategy. Choose defense strategy for your towers smart and you will prevail in this defense game.

This is what happens when gamers make defence games. We make offline tower defense games that we would enjoy. 

What I urge you to play today is raw and epic rush of TD strategy game experience of trying different defence and tower strategies upgrading your defense and finally winning. Want to play strong defence game? Build scary flamethrowers. Want to play tricky defence? Use your strategic thinking and construct the defense that confuses and plays with the enemy. Want to play wise and resourceful defense? Insert economic modules and get as much as you can in tower defense games from your nemeses. Strategy is important here because the resources available to achieve these goals are limited.

  1. Tom Coakley-avatar

    This should be a five star game. The tower module system is very enjoyable and challenging to start. Unfortunately game balance is off and at least one tower is wildly over powerful. You will know it when nearly all enemy die before they become visible on the screen. I continued to play by not using that tower, but play seemed to be on the easy side with other towers too. Well worth playing.

  2. billy jean111-avatar

    Workshop upgrade combo of weapons. Its been "hell + too complex. Combo insertions of weapons I am talking about. Good luck !!! Too complex !!!!!! Uninstalled the game. Goodbye !!!

  3. Lan Mai-avatar

    Game is good and challenging, been playing for over a week. But daily rewards stops on the 3rd day. Keep coming back but says to come back later. Please fix

  4. Michael Mcclung-avatar

    Michael Mcclung


    I did rate this 5 stars, it was a good game, but it keeps crashing on hard level 7 wave 7 for some reason. Please could you fix this issue

  5. Ozan Akten-avatar

    Way too complicated. Need to memorize module functions. Bored. Btw why no ejecting inserted ones? It would be better if we change modules and create dynamic towers DURING GAME...

  6. Jack Peñaflor-avatar

    How bout an update for endless/level/new maps? I already finished all maps and levels for 3 stars, I can't wait for more! Love this td! Kudos!

  7. KSI N3XUS 7-avatar

    Loved the game switched phones and lost everything... please write back if theres a way to get all my purchases back.

  8. Scott Carter-avatar

    Kinda hard to keep different towers and modules straight, but super adictive once you do.

  9. David Griffin-avatar

    The game works fine and the gameplay is fun! Recommended

  10. Ricky Frenette-avatar

    Fun and challenging. Unique but appealing tech tree desing.

  11. Benjamin F-avatar

    First planet plays pretty well. The game definitely has some bugs and crashes are frequent (especially playing on fast speed). Real problem is when you get to the second planet. Suddenly, your great towers are barely adequate and most of the mobs don't give money to upgrade. (Bug?) So they're either hoping you'll pay to upgrade your towers enough to continue, or it's just bad design. (Not sure which.) Ok for a fling, but no staying power here.

  12. Rufus Wright-avatar

    Decent enough TD game but not 4 star. While the modules allow a lot of variety the AI is pretty glitchy and it's very easy to cheat, also not enoughinformationfrom the wiki/informationsection. Needs some TLC on the AI and wiki and work on some of the levels.

  13. jed defriend-avatar

    Brilliant game n love the concept of it but hit a major snag now got to the third planet n can't play any further. Can't place platforms anywhere n platform price is stuck in top right hand corner with 9999 on all four items, have uninstalled n re installed to no avail hopefully the developers will address the problems soon

  14. Peter Ward-avatar

    Its dicficult and takes a lot of thought into winning which i like. Makes for fun and challenging game time. So far its worth a 5 star.

  15. Peter Duff-avatar

    Moving 2 new phone is challenging. Data doesn't appear 2 backup very often so logging into new phone doesn't copy everything across. No option 2 force a backup so it is easy 2 transfer all gameplay. I am playing on hard but cloud data says I haven't finished the easy mode.

  16. Victor Espinosa-avatar

    Victor Espinosa


    Not balanced. Game requires too much grinding just to get through lvl 5. Or requires purchase. Not a fun experience going through levels over and over again to mine enough to move forward. Toomuch work, not enough reward.

  17. Michael Lewis-avatar

    Great game, but when i get to world 3, mission 29, the map shows up but nothing happens and nothing is selectable. Basically stuck and can not advance. Tired force stopping game and restarting phone but the issue remains.





  19. King Raeror-avatar

    I prefer a contsant night mode that really lights up the towers. Havent played through it all, but high end towers need a nerf or enemies need a buff. They become game breakers real quick if you know what your doing.

  20. Gunner Za-avatar

    Cool game with awesome tech. But easy and small maps. The text is not in proper English and messages confusing. No help on module updates in library.

  21. Beetle Bottle-avatar

    Horrible game, and graphics, towers suck, and modules are difficult to understand.

  22. Eric Johnson-avatar

    It's a cool game but the levels get super hard all of a sudden and cannot be won. I don't want to play something that's impossible.

  23. Mark Daniel-avatar

    Kind of complicated compared to first game. Sometimes simple just shoot stuff is fun. The new towers are fun

  24. william scerini-avatar

    william scerini


    Way more things to do than modular td. Too many options. Enjoying just the same just much harder.

  25. Erik Willis-avatar

    It's hard to play and I love it. Normally similar games offer an amazing clicking experience, but playing this one you'll never win by just non stop clicking. Appreciate

  26. David Austin-avatar

    Excellent game, I liked it because it's really addictive. It deserves five stars overall.

  27. John Long-avatar

    It's colorful and easy to play. Simply the best game of its kind. Appreciate 👍🏻

  28. Brian Briggs-avatar

    Truly awesome game, it's very addictive and also challenging. Highly recommended!

  29. Peter Grant-avatar

    It keeps me hooked, I just wanted to find an interesting game and I found one that totally good

  30. shadowmartinez9489-avatar



    Best defense game I've ever played. I would totally suggest this game to anybody and everybody. It's that great.

  31. Aaron Brucker-avatar

    Good game wish there were endless missions and a way to get more starter energy per mission

  32. Simon Poole-avatar

    The best TD out there. Playing this one doesn't seems like just wasting time, brains required 👍🏻

  33. Hyper Yeti-avatar

    For a freebee it's a good little game =)

  34. Joshua Blair-avatar

    This game is a great time killer, it's exactly what I was looking for! Love it

  35. Beatriz Rodriguez-avatar

    Beatriz Rodriguez


    Its a good game the graphics are cool and looks furturistic

  36. Jason Lee-avatar

    I absoloutly loved this game and the first one they made. So many new towers and combos and enemies. Once I was able to figure out stratagies and towers, I went on to figure out what works best and beat the entire game without purchases. One of the most amazing free to play games for tower defence. This is a must download for hours of fun. Make sure to upgrade towers and find all the combos.

  37. Sam Benson-avatar

    Couldn't even get myself to complete the first level. It's a very ugly perversion of the first game. Why did my gatling tower turn into a gauss tower? Why does everything look more like it's a cartoon network kids show, in this version? The first game was already cartoony enough. I don't dare find out if it has dialogue worse than the first game.

  38. Balas Hutava-avatar

    I adore such games that keep your brain busy and doesn't allow you to just clicking a screen to achieve something. This game is a real deal and it's free so I'd recommend it without any doubts

  39. Danko Hupkol-avatar

    Normally I don't play on my phone but this game really hooked me. It's simple but it keeps you entertained. The big plus is that this app doesn't glitches on my outdated phone

  40. ZPigMLG-avatar

    Excellent game, with many features and possibilities of the modules, creating a special experience. The game is confusing at first but the encyclopedia is helpful in that way, as it is basically full of information. Graphics and controls aren't good as some of the others, but it isn't bad either. More features would definitely make this game better. Overall, this game is fun in one way, but can still use some improvement. I think this should get 5 stars.

  41. Celín Reyes-avatar

    Awesome game, I already completed all the levels, so all I ask from the developers is to double or triple the number of levels and, if possible, come up with more diferent planets and races of enemies.

  42. Patrick Adams-avatar

    found an awesome way to gain extra energy. Love it.

  43. J D-avatar

    Do not be fooled by how shiny it is. Whomever designed the modular towers system is awesome. But once you get to the second planet you will realize that this game is awful. I cannot believe that most people make it past planet 2 map 2. The game design is so lazy and greedy (they really should have just charged $2 for the game instead of making the game's design so embarassingly cheap) planet 2 map 18 for example. What a let down, so much wasted potential. TLDR do not waste your time!

  44. PeaceProsperityPleasure-avatar



    Great game and challenging until you realize the system. I have completely beat it on hard mode and would enjoy a new update with more levels!! Also game is easily played without spending a dime.

  45. I Love YouTube-avatar

    Great tower defense game

  46. Damian Tennyson-avatar

    Damian Tennyson


    Fun so far! Few ads

  47. Rohit Phadtare-avatar

    After playing various lvls I found, u need to specify, which kind tower affect which category in upgrade menu. Module need to be ezy to Identify, in game everytime I want to upgrade, it shows 2 icons, it make hard which 1 I have upgraded, and y very few alloted slots to Build twrs? the hell u deciding Already where we should build the towers , make area free to build twrs

  48. Graham Demetris-avatar

    Graham Demetris


    Honestly the best tower defense game I've played for a very long time, regular improvements definitely contributes to my positive opinion. Play this game and you'll know what I'm talking about!

  49. M Wilson-avatar

    Though in it's early stages these devs have again produced a great TD game. It took me a while to get my head round how things worked as a lot has changed compared to the first game. If you are looking for a simple game this may not be for you, but if you like being challenged & having lots of options then you will enjoy it. The graphics and sounds are highly atmospheric and a real pleasure. The devs are receptive to player feedback. It can only improve & is already a fab little game.

  50. Timmos Terhyou-avatar

    One of the most enjoyable games right now for mobile. Works great on my phone. Recommended.

  51. Ferty Asderty-avatar

    It has good graphics and offer a hours of playing, you won't stop playing this

  52. Bob Bob-avatar

    Still buggy! Game crashes when you max out the fire rate, fire range or the number of turrets (I originally said this was due to lasers having a really high starting fire rate). The game is fun😍. Finding turrets is still tedious, perhaps it could give you the 'recipe' once you have all the necessary modules. The game can still be beaten spamming just mortars (all 19 levels) but I do like the double laser although they do crash the game (really high fire rate). 1 extra star for the improvements

  53. Tiko Golli-avatar

    This app is certainly my favorite game to play while commuting to work, give it a try, you won't regret!

  54. Ginnko Rettu-avatar

    Without a doubt one of my favorite games. It's quite difficult at first but really fun as well.

  55. PhoenixHellResort-avatar



    game is very good. early game is a bit hard but once u get the hang of it. it becomes quite easy on certain tactics. ps i noticed that soul stealer lvl 3 nerfs other turret builds way to hard. dmg of turret goes from 500 to 200 speed also reduces. i did read there where some fixes but atleast ill give this info. 3mod schematics are the best in my opinion due 2 free slots u can add freely. there is also a nice economy build for long tracks. very tactfull

  56. 7-avatar

    I like the previous one more than this one. It feels slow to me. The mechanics is still unbalanced with periods of you being over/under powered. Combo modules to form a specific tower units seems annoying as you need slots to upgrade your units. But overall, I love this game. It is a unique gamestyle you cant find anywhere else.

  57. Wiktor Gorzynski-avatar

    Wiktor Gorzynski


    Just finished the hard mode and could use more levels and couple different endless modes to lengthen the experience. Modulating (researching, collecting, testing, refining, upgrading modules and combos) provided a nice counter-balance for the main game. Levels were quite challenging during the easy mode and a couple even surprised positively on hard. I would've expected more from the last 10 levels on hard though since by then I had grinded myself a big fat splash tower with money-making support towers that were a bit too strong for the filthy space aliens and bugs and robots. Would recommend to any TD games enthusiasts, download and modulate away! Seriously, endless mode(s), now please! :)

  58. Mark Menson-avatar

    If you're looking for an interesting game then look no further this is the most challenging game I've tried lately

  59. Rainbird 78-avatar

    First game is by far so much better. This one needs lots of changes to make it better but the changes will not happen. Uninstalled.

  60. trakti N-avatar

    The game is awesome in terms of possible strategies. I can't keep myself from trying new stuff. however it may look hard for new player so don't give up. I hope devs will add more feature in the future or a new race. Good luck anyway. good job

  61. Peter-avatar

    compared to the first part of this game the game feels a bit slow. also the constant up arrow things in the bottom where u could put an extra booster is pretty annoying advertisement. Also please hire someone do an English check on all texts in the game (part one could also use one of those)

  62. Mark Atkinson-avatar

    awesome game but not enough levels to keep you going for more than a few weeks, also just like the first game the descriptions are poorly written and its obvious that english is not the game makers first language, improve on your english and write better descriptions "copies the mode wich left of the prismatic mirror" is a horrible one and means nothing to me but word salad, apart from that its a great tower defense which is why i gave it 4 stars - its easy a 5 star game with polish

  63. McDermott Hazle-avatar

    McDermott Hazle


    Just amazing! LIKE THÉ BEST TOWER DEFENSE GAME! this game shows and is proof that good games exist... so far it's my favs. in the whole play store. you will love this too

  64. Colin W-avatar

    A poor copy of the original game. Every combination of towers and upgrades I have produce no results. The speed upgrade actually slows one of the towers down, and on one level the mobs come out so fast that even when I kill one per shot several still get through. This one is not worth the effort.

  65. Brian Lloyd-avatar

    The new towers took the game to a new level, what a challenging game! For me, it deserves five stars.

  66. Erwi Dert-avatar

    The new update fixed a lot of bugs and now the app runs smoothly on my Android tablet. Great game!

  67. Benjamin Smith-avatar

    I have to give it 5 stars! I like its futuristic aesthetics and how flashy it can get sometimes. Amazing game!

  68. Osla Micheal-avatar

    This games very well done. Some nice, fresh ideas too! Perfectly playable without in-app purchases.

  69. Paige Reiser-avatar

    Wish their was more ways to earn crystals

  70. Steven Perry-avatar

    Probably the best defense game I've played in a long time. It works amazingly on my Android tablet!

  71. Billy Boom-avatar

    This game is truly epic. These towers are powerful, almost like enemies themselves! Totally recommended.

  72. Casper Born-avatar

    2/10 first game was better, why such a drastic change in UI, it was simple but clear in the first game but now it's overdesigned and some of the text is really small. definitely don't recommend it over the first game, do play that one though good game.

  73. Sarew Werhui-avatar

    I like the look-and-feel that this game has designed. Everything looks neat and modern!

  74. Amzar Nacht-avatar

    nice game... for tablets. text horribly small on phones, unlike original game. modifications to towers is novel and takes getting used to. some levels untouchable without upgrades far ahead of game progress. ads are unobtrusive, which is nice.

  75. Charlie Chew-avatar

    the game is good. but when loading to start the level. the loading is forever most of the time. gets a little lucky if able to play 1 stage. so have to reload and reload the application n maybe waste 20% of battery to play a level

  76. Sean Horgan-avatar

    on 2nd planet, 2nd level, wave 2: games currency per kill craps out. no incoming money, it just sits there and blinks when an enemy dies. UPDATE - dev staff responded and explained: some monsters do not drop energy. thank you for prompt response!

  77. Christopher Allen-avatar

    Christopher Allen


    I've spent so many hours playing it. Once you start making modules you totally know it's an exciting game!

  78. Mhelfranz Borlado-avatar

    Mhelfranz Borlado


    It is an amazing tower defense... it greatly challenge me... amazing gameplay, unique set up of tower style and its very very hard to clear every stages... tumbs up to the developer of this game... hope to update more towers... thanks for the amzing games guys.

  79. Sabrina Wertad-avatar

    Good gameplay and graphics overall. I like this app and the way it works on my Android smartphone. 5/5

  80. Jacobi Graham-avatar

    Very nice tower defense game. Hoping more worlds will be added soon!

  81. Garry Doyle-avatar

    Hands down, this game will give you many hours of entertainment because of all the opportunities it offers. Highly recommended

  82. Tya Asbim-avatar

    When you start combining modules, that's when the real magic begins! Awesome game!

  83. Mark Kelly-avatar

    I just started playing it, but I think it's very cool and original. At least, it doesn't look like anything I've played before. 5/5

  84. Bryan Burnworth-avatar

    Bryan Burnworth


    Great game! Looking forward to new levels. Only problem I had was the Laser module would cause the app to crash. Also you might want to add a "hard" level to the game.

  85. Sara Kawin-avatar

    If you like challenging games, this one is a must. My boyfriend introduced me to it and I'm so thankful for that! :D

  86. Chris Dickey-avatar

    so the bad guys keep getting stuck at the orb dispenser

  87. Ammi Dertas-avatar

    What a interesting game! Once you get what's it all about, the addiction begins... Two thumbs up!

  88. Butch Mills-avatar

    you could add an exit and the weapons aren't what they should be to have a chance of winning disappointed! could be a great game! the more you upgrade weapons the less they work!

  89. Kenneth Goudge-avatar

    Awesome gameplay but costs too much to upgrade and having to grind the same lvl over and over at early stages for 1 tower upgrade makes it very tedious. Have been stuck on lvl 1/6 for over a week grinding and not looking likely that I'll be moving on for a while unless i pay for materials

  90. Ralph777-avatar

    Awesome features but the upgrade is too expensive. And the healer enemy tanks are too much. Its too invincible when they are a lot. I'm being overwhelmed even if my towers are in high upgrade.

  91. Cassin Erich-avatar

    Very fun and a lot of different gamemodes, takes some grinding but its a lot of fun

  92. Ingz N Ricky-avatar

    Like the game. It just sucks that I've finished the game. I've got all levels cleared in both normal and hard mode with 3 stars. There's nothing more for me to do.

  93. Michael Sparrow-avatar

    Michael Sparrow


    Great game, spent quite a few hours playing it, one of the best in the genre only problem is later on it feels very much pay to win..

  94. Jacob Brown-avatar

    Lots of bugs still. Crashes almost every level if looking at towers attacking units and playing video after level complete. Would rate 5 star if game was built for an older phone.

  95. Dempsey Alford-avatar

    you make it impossible to defeat levels, planet 2 level 2 the mobs don't even give energy. how are you supposed to beat that? you don't get enough starting energy to upgrade a tower to get energy...weak. i challenge the Dev to beat this level and post it.

  96. Joshua Kirkeby-avatar

    Great game. Focus upgrading one tower to hit them hard

  97. John Berry-avatar

    Packed with action and new challenges everytime I play it. This is an excellent game!

  98. Larson Matilda-avatar

    Love it! Beautifull and sometimes difficult game. Really challenging and fun

  99. Butch Mills-avatar

    you don't get enough money to start with !! Upgrades are really weak. its a waste of time playing a game whos weapons are really weak the more you upgrade the slower the weapons fire!

  100. Elyse Knipp-avatar

    Pay to win, can't see much, darken the price on upgrades, would be nice
