Stadium is an urban, medium sized map. The map is set around, and partially inside, of an ice hockey stadium and the nearest buildings.
The map is very tight and includes many close corners but also has wide open spaces, including the stadium itself, the fountain located outside, and the area behind one of the buildings. Most of the combat takes place near the fountain, on the scaffolding, and inside the stadium. There is also a shop that sells various items such as magazines.
Although the map is based around close quarters combat, there are locations set up for long range and medium range combat.
During four-player local split-screen, the third player may have a completely white screen, ability to noclip, and spawn in an inaccessible area. Ground appears during a killcam and when a game ends, but is completely gone otherwise.
The logos on the Stadium bear a resemblance to the old CBC (Canadian Broadcasting Corporation) logo.
The team which Stadium is the home rink for is the fictional team, the "New York Atomics."
Stadium is a rebuilt version of the scrapped map Münich.
In the bookcase in the building by the Black Ops spawn, there is a book labeled "Edward Richtofen." This is found in all bookcases in any multiplayer map.
If a Tactical Grenade is thrown into the hockey rink, the score board will make a buzzing sound as if a goal was made. This also happens if the scoreboard is shot or damaged by explosives.
While the rest of the stadium has row chair seating, benches are only present where players enter the main stadium.
The postcards in the souvenir shop spin when shot and spin faster for each round shot.
There is a magazine called "File" around the stadium and, like Life magazine, it has a special "the year in photos" issue. If one looks closely, the words Vorkuta, Laos, Cambodia, and Vietnam can be seen.
Throughout the map, there are many posters referencing the 1972 US presidential election.
The hockey puck (found in the middle of the ice rink) can be shot into the net, but nothing will happen to it if it goes in.
The map may be based around a fictional ice hockey stadium in New York called "Chance Stadium".
If one no clips outside of the map, they will find that all of the vehicles are low quality and are blocky.
