Add trip-wires to the traitor buy menu. Makes for fun trap setting and more explosions.
Aswell you can implement TTT upgrades to prevent setting it off yourself etc, similar to SGM.
One in the chamber, everyone starts with a pistol (Deagle) and it has one bullet. They also have their crowbar. Every kill they gain 1 more bullet in their gun.
Simple, yet super fun. Would be a great addition
