You are the probe, and your mission is to maneuver your way to the other end of the warp tunnel. You are equipped with two shields, one to protect you from icy drones, and another from fiery ones. However, only one shield can be active at a time. WARNING: Be quick; your nerves will be tested. Please post all support issues in the forums for the game.
Very hard at first, but after some time becomes quite enjoyable. Difficult to master in any case.
