A small black square traveling through a three-dimensional world discovered a road that goes into the distance through a tunnel. You in the game Xtrem No Brakes help your character to go through it to the end. Your hero will slide along the surface of the tunnel gradually gaining speed. On his way will come across various obstacles. Between them will be visible passages. Using the control keys, you will have to force your hero to go through; do not reduce the speed through these passes. If you do not have time to react, then your box will collide with the barrier and die.
