About this game

Robo Defense is the ultimate portable tower defense experience. Featuring open maps, upgrades, achievements and nice graphics.

The full version features 5 maps with unlimited upgrades and difficulty levels.

A free version is also available (try it first!).

Free version progress is automatically imported into the full version, should you choose to upgrade.

HTC Desire, San Francisco: Turning off "High Quality Graphics" fixes known issues.

Galaxy S: Turn on "16-bit Backgrounds" to fix studdering performance issues.

Atrix: Disable sound to improve stability

Performance tips: If the game is running sluggishly, try playing fully "zoomed in". Turning off "High Quality Graphics Mode", in the options menu, will also help on some phone models.

Ratings and reviews

I have played for years through many devices. no ads or in app purchases. Even the blank and VR maps are replayable at increasing difficulties. love grinding for upgrades. I will get many more years out of this game. Its almost like a stripped down Defense Grid (complimentary), and I use it as the base comparison of playability when I try other TD games. This is My Favorite Mobile TD Game.

And the dev team are absolute legends! New update fixes the scaling issue on my S21+ as of 8/31/26. Amazing game, lost count of the hours I've played across 3 different phones. Update. Love this game ever since I installed it on my galaxy s3. Recently started crashing and figured it was the end as it's an old game that hasn't seen an update in years. To whoever fixed the crash bug and took the time to update this game in the play store; thank you! You're my hero!

I've been playing Robo Defense "forever". Every game is different and every game is fun. Love it! 8/16/26 update issue: The top most icons cannot be changed once they are installed / put in place. If you fully zoom the slider to the right, then you can change them. 🤣 I tried all my resolution options...same problem. Now....I am running the latest beta version of the next Android OS. So, maybe that could be the problem?
