http://www.indieroyale.com/This bundle includes Nuclear Dawn. We should all have this and be playing vs each other. I got a bunch of people to buy it on Steam, and now it's on indieroyale (also activates on Steam) for around $3-4 based on when you look, so it's worth it! Good class-based FPS action + RTS commander role (you never need to play the RTS part). Like Savage, or Natural Selection. Oh and there are other games in the bundle too.
let's do this!
