Some new details for UC have surfaced.
According to Yoshi Sato at 1Up, Umbrella Chronicles has been confirmed for 2 player co-op mode in the latest Famitsu weekly magazine.
Also confirmed is that players will be able to use grenades and other explosive objects in the background to kill multiple zombies (and presumably other enemies) at once.
The location the players will start in is determined by which character you choose. Such as choosing Rebecca will have the player start in the train cars as in RE0.
