Yeah. I created it.
I took the Ascension map made by Abstyler and modified it. I placed a warthog at the top of the tower, trapped it, made it indestructible, and you’re only allowed to get into the gunner seat. That way no one can remove or destroy the turret. When in the gunner seat you are also inside a small hill earning one point for each second.
You can use the game type I made for it or make your own. Both are in my file share.
Edit: One thing I literally just thought of is the turret can rotate and kill enemies coming up the stairs so I will place a wall or something. Feel free to make your own solution to that problem. I will modify and re upload to my file share again once I fix it, eventually.
