FreeDroidRPG

The game tells the story of a world destroyed by a conflict between
robots and their human masters. Play as Tux in a quest to save the
world from the murderous rebel bots who know no mercy. You get to
choose which path you wish to follow, and freedom of choice is
everywhere in the game.

FreedroidRPG features a real time combat system with melee and ranged
weapons, fairly similar to the proprietary game Diablo. There is an
innovative system of programs that can be run in order to take
control of enemy robots, alter their behavior, or improve one's
characteristics. You can use over 150 different kinds of items and
fight countless enemies on your way to your destiny. An advanced
dialog system provides story background and immersive role playing
situations.

The game is complete, fully playable, and can provide about 10 hours
of fun. It is still being actively developed, and help is welcome in
many areas. People having - or trying to acquire - programming, map
editing, or writing skills will find FreedroidRPG to be an exciting,
fast-moving project in which they can fully express their creativity.
