Apparently Call of Duty 5 is going to have four-player, drop-in-drop-out co-op play for the 360, PS3 and PC versions of the game. And the Wii version is going to get "a unique co-op mode for two players". The game will also have a "scaling difficulty ranking", based on your experience rank and the experience ranks of your friends. The game is going to be set in the European AND Japanese theatres.
This actually sounds interesting. Are any of you who have been thinking about not buying this game because it's WWII going to think about buying this game now?
Personally, I was already going to be buying this game, because I just love the Call of Duty franchise,
Here's the original article. It also has some nice screenshots.
