Competition Doom

Competition Doom, otherwise known as CnDoom, is a source port developed by Zvonimir Bužanić which focuses on features helpful for speedrunning. It is intended as an alternative to the long-running COMPET-N, which requires players to use the original DOS version of the Doom executables; something that is difficult to accomplish on modern computers.
