Crossfire

Crossfire, originally called Speedball during development, is a Halo 5: Guardians multiplayer map. It is set in a UNSC orbital training arena with a holographic floor. This map is dedicated to the gametype Breakout, in which players begin the game by being propelled into the arena and have no respawn.

Trivia
Crossfire's development name "Speedball" came from a type of competitive paintball with inflatable bunkers played by Halo's multiplayer design director Kevin Franklin, which also heavily inspired the Breakout mode itself.
