The battle against the Bugs moves to the watery planet Hydora, where Rico and the Roughnecks again come to Carmen's rescue when she is stranded while evacuating wounded.
Rookie troopers Rico, Flores and Jenkins journey to Pluto as part of Alpha Team "Razak's Roughnecks" on what is supposed to be a simple mop-up operation, but find a major threat to the research stations from plasma-shooting alien Bugs.
When the Roughnecks pick up a distress call from pilots Ibanez and Barcalow, who are under attack at a research outpost, Rico risks the safety of his own squad to save Carmen.
