While the game features various enemies seen in first person shooters, such as soldiers with chainguns, blasters and rocket launchers, there are also many other oddball enemies, like witches, clockwork toy rhinos, zombie stockbrokers with shotguns and suicidal exploding clowns. Different chapters feature native "chapter specific" enemies; for example the Kleer World features Flying Kleers and the Oriental setting of Chi Fang features Martial Arts Zombies. The players will also meet non-player characters (NPCs) throughout the game. There are five different groups of NPCs in the game: "The Sirians", the "Simbas", "Zixies", "Chi Che", and "Elvians", each native to their respective planet. The different groups of NPCs help the player throughout the different settings of the game, with each group of NPC corresponding to a different setting in the game.
