Bah. At least I liked it. It's an online (completely lag free), 2D, space shooter. It's a lot more complex than just shooting the asses off eachother though. Some servers (referred to as arenas) have it so you have to collect "flags" (in the game, little blue orbs) and keep them from the opposing team. Some have it where you just kill, though. It's a really fun game to play in your free time.

I play on the Extreme Games server, and sometimes Trench Wars. Post what you think of the game.
