Celebration is a multiplayer map in Call of Duty: Modern Warfare 4.
Celebration is best suited for an Assault Rifle as it is a map with long, medium, and close ranged areas. It is suggested to have an Assault Rifle with good accuracy and rate-of-fire, like the TAR-21, ACR, F2000, and AK-47. The AUG-HBAR or the M240 can be used as an alternative. A Sub Machine gun such as the MP5K or P-90 also work well for these crowded halls. Running though the halls with a shotgun such as the SPAS-12 is good too. With these the player can take out others at any range. Snipers are also welcome on the map with great sniping positions like the building with the Mounted machine-gun facing the first and top floor of the middle row of buildings (this can be a campers paradise). The best sniper spot would be on the Cuban spawn point, as the Ranger team tends to funnel into the center. If you do this right you can rack up a massive killstreak, so long as you watch your flanks occasionally. The Riot Shield can be used very effectively on this map as you can just stand in a door way and force the enemy to come to you or run around smashing other players. This map has many alleys and turns so running into another player of the opposing team will normally mean getting a knife kill/killed, or open fire combat, therefore Marathon and Lightweight are not as effective in this map as others, while the Commando perk may be able to save your life in the tight areas.
Due to a majority of the fighting taking place indoors, and outdoors, the Chopper Gunner and AC-130 Gunner may have little, or a massive effect. It maybe wise to change your killstreak rewards to UAV (counter and normal), Care Packages, and Sentry Guns just in case most of the fighting is indoors. Predator Missiles suffer just like the Gunner rewards with fighting taking place indoors.
