D/Generation

D/Generation is an arcade adventure computer game with puzzle elements, designed by Robert Cook. The game takes place in a slightly cyberpunk futuristic setting. 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 delivering a package to one of Genoq's top researchers, Jean-Paul Derrida, and who is happily oblivious of the carnage until the lab's doors lock behind him. His customer is ten floors away, all of them crawling with bioweapons.
