The movie Ender’s Game featured a certain zero-gravity training room where the recruits battled each other in special suits. Reddit user Aurelien-131 built a Halo 5 Forge map mimicking the layout and objects of this room, complete with zero gravity. Played on Stronghold, a team can win either by capturing the enemy base or by killing everyone on the opposing team. See the trailer below:
Movement in Halo 5’s zero-G involves jumping to ascend, and either ground-pounding, zooming in to activate stabilizers, or bouncing off the geometry to get back down. As a last note, bunching together like Ender’s team did in the movie probably isn’t the best way to win in Halo.
