As you earn your pay, you can equip yourself with additional weapons in the arming area and biomechanical implants that will make your fighting abilities superhuman. You have been granted access to the most advanced weapons tech money can buy. A stationary gun will aid in the defense of the area. You will be provided with explosives to help you gain access to the teleports from where thousands of pitiless creatures pour. Your mission is simple: clear the base at all costs. The endless darkness and the sombre, long passages of a military complex have become the abode of evil, as countless blood-thirsty creatures fill its offices, storehouses and mysterious laboratories.
