From an extensive article on the history of Halo published by Retro Gamer magazine, it turns out that Halo: Combat Evolved was originally intended as a multiplayer-only game and for a long time did not have a single player campaign , the very one for which it is best remembered.
In an interview, programmer Stefan Sinclair , who took part in the development of the first Halo: Combat Evolved in Bungie, says that the game was intended as a multiplayer game only. “Halo was developed for internet multiplayer even in its primal forms,” explained Sinclair, who told how, starting work on it in 1999, the game was slated to be a launch game for the Xbox Live service on the first Microsoft console.
In fact, even some time after development began and relatively late after the actual release, Halo: Combat Evolved didn’t have a proper single player campaign, Sinclair said, but the game worked by connecting to servers as multiplayer. pure online .
In the long special published by Retro Gamer, therefore, this less known aspect emerges in the history of the development of the first Halo, rather unsuspected considering how the Campaign turned out to be so incisive and well built.
It is clear that Bungie first focused on building the gameplay mechanics with multiplayer in mind, and then introduced a single player campaign with story within a game structure that was now well established and probably part of the secret lies in this. of the success of Halo: Combat Evolved. In a sense, such an approach can be found today with Halo Infinite and its separation between single player and free-to-play multiplayer.
