Parallax

Parallax is a Halo 5: Guardians multiplayer map intended for use as a Forge canvas. The map was released as part of the Cartographer's Gift update on December 16, 2015.

Overview
Parallax has no actual terrain, but does have boundary markers which disappear during games. In Forge, players can change the map's skybox to one of four appearances: 'Blue Planet', 'Halo Ring', 'Exosphere' and 'Ascendance' - an unknown blue celestial body, the center of Installation 04 (taken from the skybox of the map Truth), the Urs system, featuring Sanghelios and its moons Qikost and Suban in the background (much like in the opening cutscene of the campaign level Swords of Sanghelios), and a cloudy area with mountains below (taken from the opening gameplay section of the campaign level Genesis), respectively. 'Ascendance' was added via the Hammer Storm content update on February 24, 2016. This update also increased the map's play area boundaries by 20% horizontally and 45% vertically.
