Heres how you escape arkham city
you can go to a building lege or a bilboard (bilboards works best)
start taping 5 and don’t stop, batman will start movinng foward, once he get’s to the lege he will start going up.
how to stop the glitch
Now of once you escape and try to return to arkham city the game will bug out and you will just fly throuth eveything. there are only 2 ways to stop the bug, you can just stop flying and let batman fall untill he dies or you can just restart from a checkpoint and you will be back in arkham city.
