About This Game
Navigate trap-filled tombs like an adventurer. Slice enemies and collect an array of gems while avoiding a grim ending.
Kingdom Run VR is an action-adventure runner aiming to help you exercise while collecting lost gems. A room-scale VR experience, Kingdom Run VR requires full body movement to dodge a wide variety of traps.

With increasing difficulty challenging travel across 4 themed tombs: Prehistoric, Egyptian, Yagura and Aztec. With challenges in each level, help fill your office with all the idols needed to prove you are the best adventurer.
Turn up or down the difficulty as much as you want with endless mode! With your choice of difficulty, modifiers and customisation make Kingdom Run VR personally suit you. But be careful as each tomb is randomly generated!
Prove you are the best adventurer in the world! Score the highest distance in Endless and have your name etched in glory!
With modifiers such as one life, double speed and one sword if you feel like the tombs are too easy for a pro like yourself you can increase the challenge!
With 12 weapon types, 4 tombs types and 4 enemy types you will need to collect a lot of gems to unlock everything in Kingdom Run VR.
