This is another way to skip Aim For The Heart. Compared to the old route, it's quicker by 15 or 20 sec. But it's a very dangerous path, with black screens everywhere, tricky jumps, and many ways to get stucked in gaps between high gradients and scenery. For an hypothetical live run I recommend not to use it, because a fail would be painfully punishing.
So, when I first found this OOB, I used it to reach faster the other OOB path ThinksTheClown had found in the first place. He would get OOB by the right bank, and keep going over it. I would get OOB by the left bank, then cross towards the left bank. My route was faster than his, so I was happy at that time. But it's only now that I figure out I could have kept on the left bank ; and know what ?... it's 10 sec faster.
Dang. Looks like the trandos might shoot you in RTA though, so perhaps it's safer to do the old route if you're really low on health?
flashbang is your friend. The blind trandos really dont cause much trouble...
and the great tour takes forever, are you a real speedrunner ?? ;D
