Co-oprequired

(Maps tagged with Co-oprequired)

Some form of co-operation is required in order to complete the objectives in these maps. So you'll need at least 2 players, although a few maps may require more. While you'll probably encounter typical co-op scenarios like climbing on one another to reach a high spot or using multi-person buttons, many maps weave co-op gameplay into a variety of puzzles.
