ChainStaff

Our planet is under attack from the Star Spores, and they've warped life on Earth into ferocious uber-bugs. Even worse, a nasty alien has made its new home directly attached to your head. But it's not all bad news - your new best friend has provided both the strength to fight back against the mutated horde, and control over a weapon that can tip the balance of the battle in humanity's favor: the ChainStaff. As you traverse the surreal landscape, you'll encounter your fellow soldiers, stranded in harsh environments. Do you rescue your comrades or listen to the alien voice in your head and harvest them for upgrades? If you can persevere and defeat the Star Spores, perhaps you can save everyone…including yourself. GAME FEATURES MASTER THE CHAINSTAFF Hurl it as a spear and slice aliens in half. Throw it to the ground as a shield to stop incoming attacks. Grapple and swing on just about anything. The transforming ChainStaff does all this and more, and all with one button, it’s all up
