Imagine firing up your time machine for a quick trip through history—only to have it short-circuit and dump you in Earth’s most terrifying past. No dinosaurs, no people, just the planet at its deadliest. In Kurzgesagt’s latest animated deep-dive, you’re stranded in an ancient hellscape where the air itself wants to kill you, the heat melts your gear, and the local wildlife? Let’s just say you’re not at the top of the food chain.

From suffocating deserts and monstrous bugs to fungal forests under alien skies, each era is more hostile than the last—and somehow, you keep landing in the middle of a storm. Survival isn’t about brawn here. It’s about brains, grit, and the desperate hope your broken machine kicks back in before the planet finishes you off.

This is prehistoric survival horror at its smartest.
