Deck 16 is a multiplayer map in both Unreal and Unreal Tournament, there was little to no difference between these two versions of the map. However, Deck 16 was renamed to Deck 17 in the Unreal Tournament 2004 version of the map. This version had exchanged the goo aesthetics with a lava one, and also made some changes to the layout which changed the flow of the map (added a hallway from the upper Flak Cannon to the Shock Rifle where the UDamage is located). In Unreal Tournament 3 the map was simply named Deck, it was changed back to the goo aesthetics again but kept the layout from UT2004.
The soundtrack in Deck, Deck 16 and Deck 17 is called Go Down.
