ONS-theVine is a Onslaught natural themed map for Unreal Tournament 2004 released by Tidu.
A withered-down "vine" structure remains in a grove after innumerable years. The body of water running through the map splits it in half and leaves three ways across: two outside paths or the chokepoint in the middle. Control of the center node gives the team a Paladin to add to their arsenal. Each team is spawned a SPMA at their isolated node. Three node layouts have been supplied. The default features a "figure-eight" type layout with one isolated node per team. The second layout takes advantage of most paths between nodes, and the third gives each team two isolated nodes.
