Having tracked the remaining Bull Aliens on Earth Colony Terraform 3 to a ranch, the Space Marines head inside to eliminate the creatures. The squad discovers a Power Loader before being confronted by the Bull Aliens and their Queen. The Marines open fire with their flamethrowers, but are outdone when the automated sprinkler systems activates and puts out the flames. They are forced to retreat outside, but realise that Lt. Ripley is no longer with them. The remaining Marines are surrounded outside and seem doomed when suddenly Ripley reappears in the Power Loader and joins battle with the Queen. The Marines regroup and prepare to finish of the creatures once and for all.
