Robo Defense is one of the oldest games on the Android market, and yet, it remains one of the best. Since the G1 launched, it has been a mainstay on many Android users’ phones, and even with the crowded competition other developers have brought in the form of tower defense games, Robo Defense has remained a true competitor.

That experience is about to get even better as the developer wants to inject new life into the game – they’re introducing an HD version. For now, you can only check out a limited beta that affords the player one map and 11 difficulties. When we’d be able to see this game hasn’t been mentioned, and no word was given on whether or not existing paying customers would be able to get the upgrade for free. Download it in the Android market now. [via Droid Gamers]
