Classes:Chaingun

Note: Wait! Stop! You do not need to copy this actor's code into your project! Here's why: This actor is already defined in GZDoom, there's no reason to define it again. In fact, trying to define an actor with the same name will cause an error (because it already exists). If you want to make your own version of this actor, use inheritance. Definitions for existing actors are put on the wiki for reference purpose only.
