provide me with a build and weapons and I will script this and make a gamemode and such ASAP because it sounds loving awesome
Why not a ProMod gamemode. The main thing you need to change is obv. the rounds and rules etc and also a Playertype who jumps quickly and does not have acceleration when jumping and walking. Another thing could be to make probing toggable instead of holding.
The rest is just a modeler for a couple of guns and a scripter or you could script the guns (remember they should be very fast almost like hitscans but also have an ammo limit).
Would be really cool and map makers could just make their own maps, I am working on one right now.
