MAP13: Viral Implant (Community Chest 4)

MAP13: Viral Implant is the thirteenth map of Community Chest 4. It was designed by James Cresswell (Phobus) and uses a MIDI of the Atlantica/Aquatica techno music from Need For Speed III: Hot Pursuit sequenced by Rapidkirby3k. It is based on the layout of MAP01: Sector Limits from Virus, a game made by Cresswell using the ZDoom engine, but the gameplay has been changed to fit into Doom II.
