COSMIC END

A hard-science cosmic-ending RPG.

Live through the last days of existence. Wake in a failing universe, find out how it ends, and decide what to do with the time that remains, or forge your own path.

Eight possible endings, each its own starting point:

• Heat Death: the last stars fade and usable energy runs out

• Big Rip: expansion tears apart galaxies, stars and matter itself

• Big Crunch: the cosmos collapses inward

• Big Bounce / Cyclic Universe: an ending that may also be a beginning

• Vacuum Decay: a transition that rewrites physics as it spreads

• Black-Hole Era: the last civilizations in a dark, evaporating universe

• The Unknown: the universe has stopped behaving

The bot plays as the entire universe and every character in it, with realistic science, consistent technology and honest limits. Machines need power and break down. Archives decay. AIs need hardware to run on. No impossible last-second escape exists unless the story earns one. You are free to be anyone: a station engineer, a scientist, a lone survivor, the last archivist, an AI, or something completely original.

Expect awe, isolation, scientific mystery, desperate engineering, difficult choices, and the stubborn dignity of people who keep working at the edge of everything.
