This is my map, Upsurge v2.5.

Description:
This is an updated version of my map Upsurge. Upsurge is a training facility based in a warehouse that the UNSC managed to aquire and convert. It is a Closed-Quaters training center with little open space. It has two identical bases (A and B) with staircases on both sides. There is a two level middle structure that holds the mauler. looking from B base the 3 story sniper tower is to the right with a wall blocking the sniper spawn from view. to the left is the 3 story carbine tower with needler, 2 carbines and a brute shot on the 3rd level. the third level is accessable from the dumpster in the middle of level 2. there are gravlifts of bothsides of carbine tower. in front of each base A and B there is a small room with grav lift and crates for access from the front of the base. shield doors guard the entrance, but grenades can still be thrown over top of the walls.

Game Types:
- Slayer(FFA and Team)
- CTF
- Oddball
- KoTH
- Assault

Additional notes:
Works terrific with 4v4 slayer and objective. Is decent for FFA.
