Unlike Dead Island, Dying Light doesn’t need to be rescued by the maxim that everything is better in co-op, but Techland reprises the feature regardless. Combat’s certainly made easier with extra pairs of hands, but traversal’s a different matter. No clipping means your path won’t ever be blocked by an ally, but one sewer mission’s linear path proves difficult to parse with all those extra bodies in the way. Challenge invitations appear every few minutes, both out in the world and in missions, adding a layer of friendly competition on top of proceedings. For the more antagonistically minded, there’s Be A Zombie mode, in which you invade other players’ worlds at night as a fast, agile, and quite infuriating hunter.
