Terrible Lizards is a horror parkour game set against the backdrop of an old Route 66 attraction… with something dark and sinister lurking below. To escape, you’ll need to move fast, navigate challenging terrain, and uncover what Dalton’s Dinos is really hiding. You’d better start running.
Story
There is something wrong at the Route 66 roadside attraction, Dalton's Dinos. You should leave. Too bad your car is broken down, and the sweltering heat of the New Mexico desert has driven you into the only shelter around. It's 1992, and there are no cell phones, no rideshare services, and no one around for miles. The staff is missing, and a mysterious voice on the telephone ringing in the attraction is begging you for help to find a missing child. You are not alone, though.
What is happening now
Terrible Lizards is a first-person horror game built around parkour mechanics, dropping players into an abandoned Route 66 dinosaur museum where something threatening stalks the grounds below. The game emphasizes movement-based survival, leaning on climbing, jumping, and sliding to evade threats rather than combat. The title is preparing for its October 2026 launch across PlayStation 5, Xbox Series X and S, and PC. A beta demo has recently become available, giving interested players an early look at how the parkour-focused horror concept plays out in practice.
