Dick has unique dialogue for everything, from normal zombie interaction to Side Mission dialogue. In Dead Rising 3, the co-op player controls Dick Baker. In Off the Record and Case West one player controls Chuck Greene and the other controls Frank West. Players are able to import a Chuck from their game files. In Dead Rising 2, both players play as Chuck.
This allows players to work together to defeat difficult bosses, complete cases, escort survivors, and generally play around in the game world. Co-op Mode is a mode featured in both Dead Rising 2, Case West, Off the Record and Dead Rising 3.
