The best online shooter of all time, it nails its setting and features extremely cool, well-animated, strange and obscure guns. The online battles can be either insanely large scale with massive blimps flying overhead or brutally, desperately close fighting for inches of ground in trenches and hallways. Everything about it takes the aesthetic brutality of WWI and turns it into a fun and intense game. Really awesome, no other online shooter feels so grounded in its own take on its setting.
