Often the choices made by the characters are determined by something called an Oracle – a system used to answer Yes/No questions. We’re using something called the Mythic Engine that gives us a chance for each option based on various parameters.
Mythic: Is there interpersonal drama during the elevator confinement? It’s a stressful situation, and Josh is a troublemaker, but the group is accustomed to one another. Result: 62. No.
Mythic: Will they try the hatch? 34: Yes.
While Mythic governs what the characters may try to do, whether or not they succeed depends on their character traits. Our characters are above-average teens built with 75 points each using the Generic Universal Roleplaying System (GURPS) published by Steve Jackson Games.
In GURPS you generally want to roll less-than or equal-to your skill or attribute on 3d6. This means that a trait of 10 will succeed about half the time, with a bell curve as numbers get higher or lower.
Random roll to see who checks out the hatch: Nick.
A soft noise came from his left, and Nick turned his head to come face to grotesquely mangled face of the source of the earlier crash, some unfortunate bastard who’d fallen from the doors above. His face had split open in the fall, one eye was dangling from its socket by the root, slapping wetly against his cheek.
Nick stared at it in silent horror – then it began to move, reaching towards him with one bloody hand.
In GURPS a Fright Check is rolled to test whether a character can act rationally when faced with particularly terrifying stimuli. This is a Willpower check that if passed enables them to act normally. If they fail, they need to roll on the Fright Check table to see what the consequences are.
GURPS: Nick rolls a Fright Check.
“Pull me down!” He struggled away as the dead thing dragged itself closer. “Pull me down pull me down pull me down!”
The others yanked him down into the elevator just as it reached him, and the crawling corpse fell down through the hatch after him.
Someone screamed – possibly Ashly, possibly Marco – and they all tried to flatten against the walls to get away from the thing that had fallen, squirming, in their midst, lit only by Josh’s flashlight.
“What the fuck is that?” Marco was saying. “What the fuck is that?”
“Nghaa!” was all Nick could manage, scrambling away until his back was to the doors, the corpse scrabbling at his feet.
The ground tilted, and then the elevator was falling, crashing down.
