Released in 1993; in "Space Quest V", Roger is now a cadet in the StarCon academy. He graduates (or rather, cheats through the final exam) and is appointed captain of his own spacecraft (actually a space garbage scow). The main plot is to stop a mutagenic disease that is spreading through the galaxy by discovering its source, and fighting everyone that got infected. In the end, the disease infected the crew members of the "SCS Goliath", a powerful warship, whose commander, Raemes T. Quirk (a rather blatant spoof of Captain Kirk), subsequently attacks the "Eureka". In the end, Roger sacrifices his ship to get rid of the plague – and suddenly, if temporarily, becomes the commander of the fleet's flagship.
