The Marine goes down the shaft from the previous level and ends up on near a piece of glass. Once broken, the Marine is forced to either fight off the four Human Soldiers at the top area, or go down an elevator and three enemies but also jump over an abyss. At the area where these two paths join, the Marine has to fight off five soldiers who are standing nearby barrels. Once this area is complete, the Marine can jump down another shaft where he is greeted by a lone soldier and a lone Grub. Once those two are killed, the Marine can complete the level and move to the next one.
