We've just discovered a hive of bugs infesting a Xeloxian atmospherics plant on the colonial moon Threepair. We can't risk using ship's weapons on it for fear of asphyxiating the colony. You are going to need to go in there and clean it out. We're issuing each of you any personal area effect weapon you want for use during this mission. These will be collected at the end of the mission.

Destroy all of the bugs before 10 escape into the colony.

Destroy all bugs before 5 escape into the colony.
