Chasm

Chasm is a multiplayer arena map that was included in Halo Infinite's Season 03: Echoes Within.

Universe and lore
Chasm is set in an underground Forerunner structure set within the substructure of Installation 07. Many whispers echo through the underbelly of the ring; some are from many millennia ago, and they sing their songs from darkened repositories in hidden chambers, while other whispers bemoan the circular nature of history, especially given the recent events on the Halo. Installation 07 has once again been sundered and occupied by opposing forces, the ring's shattered substructures have again been filled with the sound of combat.

Production notes

 * The layout of Chasm was partially inspired the Halo: Combat Evolved map Boarding Action, with its linear side areas separated by a long bottomless pit.
 * Chasm is based heavily on a specific segment—also called "Chasm" internally—of the Halo Infinite mission Foundation. During the Halo Infinite network co-op flight, multiplayer level designer Cliff Schuldt and a friend of his were playing in the aforementioned segment of the mission Foundation when they noticed that it would make for a fun multiplayer map. Schuldt decided to pull the space into a multiplayer level and make it rotationally symmetric so that it would work for Capture the Flag. After the map was well-received in its early playtests, it was decided that it would get the full treatment as an official map.
 * As the art team worked on the map, it was decided that they would visually differentiate each side of the map by giving one the traditional Forerunner blue theme, while the other side was given a greater emphasis on the gold element like what is seen in the Silent Auditorium.
