Gungame Bugs
Gungame has an issue where elites can't throw grenades but spartans can. In order to replicate this issue you have to play gungame as an elite and reach 16 kills to get grenades. Elites won't be able to throw grenades. If you change your biped from elite to spartan ingame there through cheat engine then it will start working again.
Another neat feature would be to add the disable weapon interaction from zombies to be a global thing in gungame for custom maps that have issues with custom weapons not despawning.
Turns out the grenade thing is a default bug with the game.
We'll probably force biped to MC to prevent grenade issues, and add the weapon interaction so that we can add dual wield levels.
