After many months of very hard work, Robo Defense FREE is now available on Android Market. The abstract will tell you most of what you need to know:
Robo Defense is the ultimate portable tower defense experience. Featuring open maps to allow countless strategies, upgradeable towers, permanent stat upgrades, a revolutionary achievement system, smooth frame-rates, and some pretty sweet graphics. The free version features 1 map with 11 difficulty levels.
The full version will feature additional maps and a lot more difficulty levels. We hope to release it in about a week or two.
As we were not first to market with a tower defense game, most people will get the gist of how to play. Basically, robots are trying to get from one side of the map to another, and it's your job to stop them by building and upgrading some defense towers.
