There are no rules
My boyfriend DM’s a group of our friends and created a homemade Cyberpunk game, complete with custom classes. I’m a hacker, there’s a theif, a sergeant, and a doctor. For some background, we wake up from cryogenic sleep into a zombie apocalypse and are forced to play a survival game by this black orb. The DM made the mistake of giving me an overpowered arm modification, called doomfist, that let me punch through walls.
Me: Can I talk to Lamar?
DM: Do a constitution saying throw
DM: He picks you up and throws you into the wall, you take 22 damage.
Sergeant: oh he’s dead, no one hurts my team
After the battle
Sergeant: I’m gonna cut his head off and take it with me, last thing we need is it crawling back together.
DM: but.. I.. uh.. Okay
DM: All the doors lock and a poisonous gas begins to fill the room
Me (hacker): I’ve still got charges on my Doomfist, so I’ll punch through the wall
DM: But, I *begins to laugh as all his plans fly out the window* okay
Later we are interrogating the man in charge
Me: Well, I give up. He won’t give us any information, so let’s just put him in the room with Lamar. He’s not in his machine that controls the place anymore.
DM: You know what!? I’m done, you guys messed everything up, just have your tanks too!
And the rest of the session was utter nonsense as I ran around in a spider tank, the sergeant had a regular tank, the doctor had a monster baby eating people, and the their crawled though the vents at will.
