D/Generation is an arcade adventure computer game with puzzle elements, published for the PC, Amiga and Atari ST by Mindscape in 1991. In 2018 it was ported to Nintendo Switch by West Coast Software with HD graphics.
The game takes place in a slightly cyberpunk futuristic setting in 2021. A French company called Genoq has developed a series of new genetically engineered bioweapons, which have run out of control and taken over Genoq's Singapore lab. The main character is a courier making an emergency delivery by jetpack of an important package to one of Genoq's top researchers, Jean-Paul Derrida (a name likely inspired by the philosophers Jean-Paul Sartre and Jacques Derrida), and who is happily oblivious to the carnage until the lab's doors lock behind him. His customer is ten floors away, all of them crawling with bioweapons.
