The Nightclub is a small slice of the Chicago map, namely Big Tony's Sunrise Club. In this version however, the Sunrise Club is fully explorable. The story mode part is still there, but the doors upstairs open to reveal the whole club. Additionally, there is a small outside area that features a back alley with climbable fire stairs. There are breakable windows to go outside, as well as an exit. All except for Capture the Bag and Assault modes can be played here. Deathmatch, Team Deathmatch, and BagTag work well in this map.
