We still don't know exactly how the game plays, or the structure of its cabinet, but a new trailer shows off how the gameplay will look.

Unsurprisingly, it looks a lot like Left 4 Dead. In fact, it looks exactly like Left 4 Dead, but with less accuracy, and what appears to be redisigned protagonists. Around the one-minute mark in the video (after the "Run and Shot" title card) there is a man in a plaid shirt that I don't recognize from Left 4 Dead, or is sequel.
