I got SR:T3rd for Chirstmas, and I finally have gotten aorund to playing the game. Anyway, I get to one mission, where I need to find Josh Birke at the Television studio, and take him. However, when the cutscene ends where you knock him out cold, Im supposed to fight off people, but the game loads with him still standing, and will just reload over and over again, as if I was stuck under something, but I'm not. I;m 13 hours in, and now I can't finish the mission. Any help would be appreciated!

Well I've restarted 3 times, and since then I've done a bunch of other missions, and have yet to retry it. however since then, my GPS stopped working on the main screen, so I cannot even locate half the stuff in the game :/ I am legitimately pissed with this game.

Yeah, that game is pretty broken. A lot of times, my GPS wouldn't target certain things. I had to target something near then and hope for the best. There was another mission where I had to destroy Killbane's casino. It took me a long time to destroy the slot machines, Killbane's goons, Killbane's statues, and a few giant flame thrower dudes.......and the game just froze.

Can't help you with your glitch, though. I barely remember that mission.

Try to play co-op with your friends who finish the game

You might have to shut off your console, and start up again. I encountered a glitch in one of the games, but it was fixed with a console reset.
