This level exploits the fact that a rocket launcher will not launch another rocket at you if it's already launched one at you. The idea here is to take the rocket with you around the level and go past the initial turret without the rocket hitting a wall. If the rocket explodes, the launcher will then fire another rocket at you when you attempt to go past it, and you will die. Currently, the fastest run using this method (according to the Nreality speedrun boards, is 560 frames. However, it is likely that faster runs were recorded on the original scoreboards, but removed due to a mass of faster runs made using method 2.
