I am currently playing the Defibrillator Upgrade part of the game and I have finished killing the big gaint, gained the defibrillator Upgrade, killed the enemies that smash open a wall and come out and then walked down to the palce where it should take me out to the wastelands.

But when I go to that place, I cannot get the 'E' mouse cursor to exit out and I am stuck. I have replayed after killing the giant a few times but I just came to the end and I cannot get out .

Please help !!

You need to practically kiss that door before you can exit.

Yeah you have to be very close to the door before it will give you the option to leave.
