Newest update: DRIVING IN MY CAR (2026-10-11)
- Cars now take damage from Dess claws and crashes—drive too recklessly and you'll find yourself stranded and on foot.
- Get overrun and you replay the same night instead of losing; the difficulty curve finally levels off after night seven so Asgore's runs stay brutal but beatable.
- Bergentruck's driving music now has clean beeps over the swears at 0:23 and 0:25, with a timer on screen so you know exactly when they're coming.
- The Dess are fewer but meaner—slower to bite, tougher to goo down, and the Roaring Knight arrives as early as night one.

@yzykyl · loved it · 2026-10-11 · played 24 min: “Fun survival wave clear but I don't think it's fair that I can survive the night while just driving around blasting this banger music LOL! The censors crack me up. It looked like another player was stressing with the waves while I was just vibing 😂”
