Arrow keys to move. Click to shoot. Kill as many zombies and gonomes as possible. Headcrabs will occasionally jump at you so be careful. --------------------------------------------------------------------------------- STORY: A headcrab outbreak has occurred in City-5. The city has been completely infested with headcrabs and headcrab zombies to the point where these Xenian lifeforms are starting to spread to other cities. Even gonomes are here and there are most likely some Gonarchs somewhere. Because of this, you and 12 other overwatch soldiers have been deployed via APCs and Dropships. Though, as the battle goes on longer your comrades start to become very overwhelmed by the amounts of zombies and eventually die. You are now the last combine left, and you must survive in order to stop the spread of Xen.
