When you've got a major infestation of Aliens, and the Colonial Marines are nowhere in sight, you won't find a better "exterminator" than Herk Mondo. But Herk's got a couple of big problems: he's completely unarmed in the middle of the infestation, and he's got an active volcano ready to blow beneath his feet! You can be sure of one thing, though -- the volcano may blow, but Herk'll keep his cool.
