First off, this isnt easy, it takes awhile, but I like the fact that you can just do it. So here goes..
In the tutorial, after you are able to enter the yard where all the free roaming prisoners are, go past them, and stay to the left. once all the way forward, the building to your left is where you want to be. Now...you have to jump on the side of the building (there is a small ledge where you can jump onto) and get to the door thats on the upper walkway. You will notice that you cant go any further than the door (invisible wall) now..log out right next to that door. Then log back in, and when logging in, try and start moving left, and towards that invisible wall before the game loads. Usually, after about 2-3 tries, you will get through. Now the fun part, after you are through, thre is still another invisible wall freventing you from getting any further, BUT you cn now jump down BEHIND the gate where the longbow and arachnos soldiers duke it out all flippin day. all you have to do is attack and do some damge to the longbow before they die from the arachnos soldiers and you'll get exp, and sometimes enhancements. Ive done this a few times just because feel special.
I'll post screenshots later only if people are interested. This forum has been kinda dead.
