Rebecca Chambers shares an item box with Billy Coen in Resident Evil Zero, Capcom's 2002 prequel made first for the GameCube. A train, a leech, and James Marcus's history sit before the Spencer Mansion outbreak, and the partner system lets one character pick up what the other had to drop.
A Wii edition later reissued that story. Herbs mix in the same pockets, and leaving Billy behind a door is sometimes the puzzle, because the two cannot always stand in the same room.
The cube original is the train and the partnership. The Wii edition is the same prequel brought back, Rebecca's lighter still the starting tool.
