No new games, catching up with the world, and filling it with the name of SpazDragon, the dragon with a spas-12.
Don't worry:
This is on the level Delta Halo.
So what I did was play through the level until I reached the point(or more like close to the beginning) where you press the switch to span the bridge across the chasm. This is the point around you get the Scorpion. I infiltrate the building the building on my side of the chasm and press the switch to let down the bridge before the Pelican drops off the tank. Exit the door as soon as you press the switch, except make a left turn.
Outside, you will see the bridge sliding down to bridge the gap, which looks like a great moving wall. Move towards the very base of this moving wall and crouch whilst moving forward, but don't stop. One of the gaps between each bridge link should catch you, and start pulling you in.
Wait for the magic to happen. However, sometimes the launch may not work, probably only because the first gap in the bridge is bugged. My best bet is to do this as fast as possible.
You will see past the map boundaries, and what appears to be a lake to right of the building on top of the hills. Trees will appear flat and clipped.
Even the birds are below your feet.
