From Halopedia, the Halo wiki
Plaza is a small, asymmetrical map with a mix of close combat and long sight lines, well-suited for Free-For-All as well as team modes. The map's layout can be described as complex and chaotic, with a diverse set of engagement scenarios and flanking options constantly keeping players on their toes. The focal pickups on the map are the Sniper Rifle, spawning on an elevated section quickly accessible via a lift, and the overshield, spawning on the central walkway above the street. The Hydra launcher also spawns on the map.
