Carney Holes

"Carney Hole" is the name given to special spots in Halo 2 Multi-player levels that would give the player a huge tactical advantage over other players. Each was designed by Bungie employee Chris Carney, the multiplayer "guru."

Carney holes are contained in many of the multiplayer levels. Some are hard to find, while others are wide out in the open. Some will contain weapons, a good view of the battlefield (and thus a good place to snipe), or just a very good place to defend.

Examples
In High Ground (Level) the towe in the base is a good example of a carney hole, it has good weapons in/nearby and a good view of the area.
