But then it wouldnt be worth any ego points Captain.
How about you go to kingshead. DO not go through the front gate.
Facing KH, jump off the peer on the left side, swim towards land, just before land, swim up to the jetty, its sorta a wall glitch right there. If you stay along that wall as you head back towards KH/island, you should glitch through, and eventually run out on the parade grounds, with no enemies.
The funny thing is, that it was posted in here already, just search for it. trade... lol
