The Wall, Coliseum in Halo 4.
Wall, Coliseum, more known as a Colosseum Wall by players, is a Forge Item in Halo: Reach and Halo 4.
Overview[]
The Coliseum Wall can be found by going to the category, "Structure," and then going to the category "Walls." It is a giant metal wall preferred by many players to forge with, instead of the regular Wall. The Coliseum Wall is very helpful if the player is forging a giant structure, since it is very large and will take up more space. However, only 50 can be placed on a map.
