Activision and Treyarch told us about their co-op multiplayer plans for Call of Duty: World at War following the game's unveiling back in June. Now they've put their promises into video form although the roughly five minutes of footage is entirely focused on two-player action (the final game is pegged to support four-player teams through the entire campaign).

So far it looks to be ... pretty standard fare. Still, with the historically high intensity of COD's firefights, it will be a huge plus to have as many as three buddies backing you up in battle. Also, as nice as co-op is, we're extremely eager to see what Treyarch is working on to (hopefully) out-do COD4's stellar competitive mutliplayer modes.
