This is a very large world, a giant gas, which has a research space station in orbit around it. It is being used for studies of high pressure and high energy conditions by Hyperdyne. Probes enter Nimbus’ atmosphere and are subjected to incredible heat and pressure as they decelerate. They then emerge from the atmosphere and are recovered by craft from the research station. The exact nature of the work being done here, and the results found to date, are highly confidential and are well-guarded by Hyperdyne.Aliens Adventure Game (1991), Leading Edge Games.
