The Space Marines head for a settlement that has failed to respond to warnings of Xenomorph infestation following the Bull Alien attack, expecting trouble. Sure enough, upon arrival they are attacked by a herd of Bull Aliens. They cut through the creatures with flamethrowers, and set off in pursuit of those that flee. They track the Aliens to a nearby ranch, where Bishop's sensors detect more than 50 of the creatures within. With little alternative, Lt. Ripley leads the Space Marines inside.
