When you get caught in the blue screen, try hitting back. It should open up a glitched team roster card. From there you should be able to activate the pause menu and select exit game. Can someone else confirm this works more than once and is not a one time fluke? EDIT: one time fluke... got it again and it didnt work
Haha, there's a way that works all the time. It's like a puzzle! Press back, press start, go to "help & options", select "tutorial". Once the tutorial loads press start and exit it. Voila!
I prefer pretending there isn't a tutorial since we can't do the Assault's waving taunt outside of it
