Installation 01 is a fan-made Halo game being made by Halo lovers working from around the world. They aim to build an artistic tribute to Halo that recreates the multiplayer experience of the Bungie-era games. The game will be free to play on all PC platforms, including: Windows, macOS, and Linux. The game is a combination of what they believe to be the best parts of the classic Bungie-era Halo games. While they mostly focus on recreating the Halo 2 and Halo 3 experience, there are also elements of Combat Evolved and Reach sprinkled in. Features from later 343 Industries Halo games can be enabled in Custom Games, but will not be a part of Matchmaking or official playlists.
