‘Halo’ on the original Xbox initially built without a campaign
Halo: Combat Evolved on the original Xbox didn’t have a single-player campaign at first.This comes from programmer on the title Stefan Sinclair, who told Retro Gamer magazine (thanks, Gamesradar) that at first Halo was going to be multiplayer-only, and that a server connection was required for the development team to play.“Halo had been developed for internet multiplayer even in its most primordial forms,” explained Sinclar.
