The latest Making of Halo 4: Infinity Multiplayer video released from developer 343 Studios reveals the game's upcoming Vortex multiplayer map, as spotted by Halo4Nation.
According to the map's description, Vortex features "ancient structures [that] somehow harness the planet's torrential wind for power." In addition, its game type is described as "Infinity Big Team Battle." This is rumored to be a reworking of Blood Gulch and Waterworks multiplayer maps.
Halo 4 is scheduled to release November 6th on Xbox 360.
