Toureon is a 3D VR first-person melee combat game. The game is set in a futuristic city, mixing elements of the historic city with modern ones from large urban and technological centers.

The battle takes place in the city, where the player should take control of a giant robot to face a fearsome enemy, a mystical monster with the sole purpose of causing destruction. The player will experience the battle from the perspective of the cabin interior, from where he/she will use the action commands to make the robot walk, attack, and defend.
