_Halo 5: Forge_ is the first time the Forge component of the _Halo_ first-
person shooter series is available on a PC platform. This free release has the
Forge mode, first introduced in Halo 3, which allows players to create and
share maps for custom maps and full game modes. Creations can be shared with
the Halo 5: Guardians Xbox One game and vice versa. It does not include any
other content from _Halo 5_ such as the single-player mode or the full
multiplayer part, but it lets players host and join custom games for Forge
maps for up to sixteen players with all game elements and assets from the full
game. Next to weapons, vehicles and game this includes prefabs, pre-assembled
collections of blocks that can be saved and shared.

While multiplayer matches are possible it did not include any matchmaking
functionalities when it was launched. Players need to exchange Xbox gamertags
outside of the game to host and join each other’s custom games. This release
contains the entire Arena mode from _Halo 5: Guardians_ with all 15 pre-made
maps to play or edit. Available maps can be browsed through a content browser.
Forge was not available on Xbox One at launch, but it was added in the _Halo
5_ _Cartographer ‘s Gift_ update in December 2015.
