Epsilon Strain - a deadly virus outbreak turned people in a facility on space into zombies. Your goal in this survival game is to kill them and clear all 5 sectors. Each sector consists of several missions, and are visible within the map. Zombies often drop energy packets. Your Armor and weapon can also auto recharge at a slower rate. After each cleared mission you are able to scavenge the area. Level summary screen will show what you have found, usually credits and mod-chips. Modding requires the supported weapon chip to be equipped. Modding a weapon chip can only be done once per weapon chip, so choose wisely.
