So, after finishing Take it Back and activating the Project Purity Purifier, I am able to watch my slides for the end of the game. After, the game does not load up the next Quest for me to do with Broken Steel. I am level 30 and can get Broken Steel items(Hellfire armor, Heavy Incinerator, Tri-Beam laser Rifle) but I am on the floor of the purifier. I have tried console commands such as enableplayercontrols and moving myself away from the site, but I remain on the floor and my character is huffing. The purifier seems to explode after awhile, and upon inspection, Sarah Lions is still there. How do I fix this? I have Windows 7 and installed the DLC's through Windows Live. Thank you!

Do you have patch 1.7? It is needed for Broken Steel.

Yeah, its fully updated. I checked Bethesda's website to make sure that 1.7 was the latest.

Umm, did you enter the correct code on the keypad in the purifier room and press -enter- on the keypad in time? If there's an explosion, you must be doing something wrong. If BS is installed correctly and you enter the code in time, you should get a cut-scene similar to the original ending, but you are revived in the Citadel.

yeah, 216, then it gives me Karma, then I hit the floor, the slides play, but then I'm still on the floor.

Odd. So, you did press -enter- on the keypad in the Purifier Room after entering 216? Sounds like something is scrozzed up. Do you have an earlier save, perhaps?

Yeah, I replayed the whole game and it didn't work. I tried once on a Steam version and once on a regular disc copy.

Are you sure you entered the code and pressed Enter before the timer ran out? The purifier explodes if you're not quick enough.
Also, are you on the floor of the purifier itself or could you possibly be on the floor of the citadel? Did you see the "Two Weeks Later" slide?

exact same problem. I have awoken in the cididel when i played other games before dont know what set it off this time
