About Crypt Raiders
Crypt Raiders is a single-player 3D action shooter set in a graveyard overrun by zombies. You shoot your way through the undead, pick up loot, and buy or find upgrades as you go, and every level is procedurally generated, so a run keeps moving into new layouts.
The creator, maybe_im_sam, says watching others start Vibe Jam 2026 made them curious whether they could make a game too, and this is the answer, built with Cursor on Three.js. It placed 294th of 945 in that jam.
The loop is about getting stronger while the pressure from the zombies builds. Loot and upgrades feed into the next fight against the undead, and because the levels are procedurally generated, the ground you cover changes from one run to the next.
