About Terrible Lizards
TERRIBLE LIZARDS is a first-person horror parkour game from WDR Studios and Behaviour Interactive. You run a desperate escape through Dalton's Dinos, a crumbling Route 66 dinosaur attraction: appraise nothing, shoot nothing — read terrain, chain wall runs, and stay out of the Hybrid's line of sight. The full game launches October 29, 2026 with Game Pass day one; a free two-part demo is already on Steam if you want to practice the loop first.
Start with the getting started guide, compare every hunter in the creature bestiary, learn the wall run and goo bounce movement tech, and track the October 29 release.
