It is a level-based runner, where each level is connected to another directly (as another part of a screen) or indirectly, through door portals. The objective is to pass the level without being killed by the zombies (which here are not very scary and do little damage). Also, there is a need to collect level stuff like floppy disks to make sure a door to another level is opened. To see how well you are currently doing, there is a counter for things and lives achieved. Also, some level locations will show you tips on what to do to make sure you're passing the level from the first or almost the first try. To shoot zombies, you have a gun and grenades. But beware! Some zombies in this free online game are not as easy to get past as they seem!
