Method 1 (Easy)
Fall down and hit the launchpad, and quickly scale the right wall. Get the switch at the very top area. The homing turret will spot you and fire a rocket. Let the rocket crash against the side of the pit you are standing in before jumping out. When you jump out, simply collide against the bounceblocks and if you time it such that you push one bounceblock out of the way while standing on top of another one, you should easily fall into the area with the second switch. Be sure not to get caught stuck amongst the bounceblocks, otherwise the gauss turrets will likely kill you. Now, if you are daring, hit the other launchpad and get into the gold area which is guarded by the homing turret. Otherwise, use the oneway platforms to jump to the exit switch. Return using the same strategy and get to the door.
