Set over 30 years after FreeSpace 2 and about 50 years after INFASA, Nostos tells the story of GTVA's contacts with the Earth Alliance and the sudden re-appearance of the Shivan threat...
The Petbe is strange even by Vasudan standards. A spiny hull design makes the Petbe rather difficult to hit from its virtually non-existent flanks, and its high speed contributes to its effectiveness in knocking out light ships. The ideal delivery vehicle for torpedoes, Petbes are often used to soften up bigger targets by destroying turrets and weapons systems before the larger bombers come in to finish the job.
