Sorry, it’s actually System Shock and Biodome.
Pauly shore and his untrusty gun?
Sequels can work brilliantly in games, though, thanks to the iterative nature of the medium - SS2, Thief 3, Wizardry 8, Freespace 2, approx 14200 obscure japanese RPGs which Kitsune mentioned and sound cool… It’s just Sturgeons law, I’m not sure the number of the sequel makes much difference.
