Even tho I can't play this game on Desura (information gathering error of some kind), I know it for a long time.
A mix of CS and Worms, quite epic even in the free version, the AI ranges from stupid to hardcore, and makes local games a veritable option.
Just passed the game and i can say that its worth its price, the story is very interesting and deep, and when you finish it it gives quite a lot to think about, in a philosophical way...
(felt that it could be a bit longer, but thats because i was playing it every day lol)
I recommend it for sure!
