Robo Defense is one of the most addictive games I’ve ever played on any platform. The tower defense game looks deceptively simple. You place different types of units on the board and fire at enemy units trying to cross from one side of the screen to the other. But as the difficulty level goes up, the game gets maddeningly difficult, especially if you don’t wisely use the few credits you earn with each game to upgrade your forces wisely.

The game’s graphics are reasonably attractive on a smartphone display. But the developers at Lupis Labs are working on an HD version which is optimized for tablets and phones with higher resolution screens. A public beta is now available for download from the Android Market, featuring 1 map and 11 difficulty levels.

For the most part, the game plays just like the original Robo Defense, but all of the graphics have been redrawn with additional detail for higher resolution displays. Best of all, the public beta is free — although you’ll have to uninstall the beta and reinstall Robo Defnese or Robo Defnese Free when the full version is available.
