"Infinity Ward let Treyarch do the tough work."
Gameplayer has gone live with an extensive hands-on preview of Call of Duty: World at War's four-player online co-op mode, which included play on both fronts of the new war.
"The rules are pretty harsh. If someone dies, the game ends and it's back to the last checkpoint. If there is mortal friendly fire, the same dealio. But it makes for more engaging gameplay as it forces you to think more about moving the frontline forward as a unit and watching each other's backs."
