Alien Breed 3: Descent

Save as many health kits as possible from the previous mission before starting the third single player mission. Also try to have the Medi Stimulant upgrade. Once the third mission begins, enter to the room next to you. Stand in the fire until you are almost dead, then step out and heal yourself. Repeat the process until you have taken 500 damage to earn the achievement. Note: Check the map if you need additional health kits. Find the nearby Intex Terminal to purchase more of them.
