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...
Also featured in INFASA, the SB Ojas-class bomber appears to be a smaller version of the much heavier SB Nephilim. It's not capable of striking capships in an effective way, but it's still a bomber to watch carefully during a battle.
