Combat Squad: Project Wednesday is an online shooter game by Korean studio A-33, utilizing a free-to-play model with microtransactions. The production is set in modern times, and allows you to participate in multiplayer battles pitting teams of trained mercenaries against each other. Before the battle, you create a five-man team, choosing your characters from an expansive gallery and modifying their skills and equipment. During the battle you can freely switch between party members, while the others are controlled by the AI, which you can affect by issuing orders using the tactical system. There are several gampelay modes to choose from. In multiplayer battles, you can fight one-on-one or five-on-five. There is also a co-op zombie mode, in which the players join forces to fight hordes of zombies.
