D/Generation is an arcade adventure computer game with puzzle elements, published for the PC, Amiga and Atari ST by Mindscape in 1991.
Something has gone horribly wrong at Genoq Biolabs, Singapore. You’re just a courier, sent to the building to deliver a package. Now you’re trapped inside, the security system has gone crazy, genetically engineered organisms are on the rampage and things look like they could get even worse… Make your way through 10 floors of isometric action and puzzles, trying to stay alive and discover what’s going on. Talk to and rescue survivors, pick up armaments and log into computer terminals. What caused the Genoq disaster? What’s inside the vital package you’ve got to deliver? What is the D/Generation? And what is really waiting for you on the top floor of the building?
