Still a work in progress. This version was primarily to get the Marine Berserker working.

I didn't like the Dark Servant artifact, so I scripted the Marine Berserker instead. Unfortunatly, that means you need to setup a key (in the controls menu) to use it. When/if you have access to him, hitting the key will drop a beacon where you stand. The berserker will teleport in at the beacon five seconds later, so you'll need to step aside. Also, make sure to drop it someplace where he has enough room to teleport in.
To fearlessly face any foe, the berserker is drugged up before each deployment. As such, he can only be used five times before his brain is completely scrambled. As his stability decreases, I'm thinking of adding in an increasing random chance he'll go rogue and teleport in a normal Minotaur actor instead of the MinotaurFriend.
