Hi,ok ive got right up to the very last save,where you meet colonel autumn and kill him,but ive also just got the expansion pack,broken steel/point lookout,is there anyway i can play expansion from this point,or do i have to restart the game? all the things ive tried,i.e. getting the girl to go in the purifier instead of me,just leads straight to the ens scene,and i cant leave as all the doors are locked.....Help please?

Have you tried playing through the end scene?

Thats how you get to Broken Steel's gameplay..

ive tried it,but as i go up the stairs the notifications come up,i ask falkes to go in,he says no,if i go in or get the girl to go in ,we die and it cuts to the end scene,also the doors are locked by then also...
