Your goal in this alien shooter is to clear all 5 sectors. Each sector consists of several missions, and are visable within the map. Progress through all levels to unlock the next sector. Zombie's often drop energy packlets. These are used as ammos (blue) and to recharge the armor(green). 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, ussually credits and mod-chips. Mod-chips allow you to modify your weapon. Mod-chops can be equipped on the equip page. Modding requires the supported weapon chip to be equipped. Modding a weapon chip can only be done once per weapon chip, so choose wisely. Use WASD or ARROW KEYS to move. Use YOUR MOUSE to aim and shoot. Press the SPACEBAR to enter doors. Use "T" KEY to teleport when done mission. Good luck!
