Chasm Ten is a Firefight map in Halo 3: ODST. Based off the Campaign level Data Hive, it is set inside the Superintendent's underground data facility.



Chasm Ten is a remarkably large map, consisting of two opposing walls, divided by a deep chasm, and connected by a number of bridges. The side on which players spawn starts out with a number of machine gun turrets, as well as a rocket launcher located in some tunnels. The map layout also boasts an additional upper level, which can be accessed by air-vents. The upper level also contains machine gun turrets on the player side. Players can expect to be attacked from the front, as well as from the sides. The map especially is a strategy map. Do you want to be downstairs where weapons lie in safety, and you have better defense? Or upstairs where you gain a greater view, and grenades won't be raining down from above?

In spite of this not technically being a 'night' map, VISR mode can be of great use to players trying to spot enemies in the distance, as well as weapons and ammo.


The side the players start on, has all of the weapons. Downstairs in the center are the rockets, on a dispenser on the wall. Directly across the map is where the extra ammo is (across the bridge). Upstairs on both sides, there are two snipers, just resting against the wall. Again, across the map, sniper ammo can be found (look for them near the monster closets on the side wall). On both upstairs and downstairs, human turrets can be found. The two downstairs are slightly exposed from their sides. The one upstairs, lack any form of protection and are vulnerable to grenades. They are however, in perfect view of two used grav-lifts. They are in perfect view the moment they come up. The spare weapons and grenades downstairs are inside of the base, allowing you to grab weapons with ease. (Also, the health packs downstairs are inside.) The weapons upstairs are on the outside where awaiting enemies are, as are the health packs.


Chasm Ten is unlocked by completing the Data Hive mission. An achievement called Chasm Ten can also be unlocked on this map if players manage to score over 200,000 points during a Firefight match.
