Ok, so i got to the vault and did everything i was supposed to but whenever i "escape" *head intact* i keep getting sent back to the suit where Christine is... I'm not sure but after this no matter what i do i cannot exit the sierra modre. can someone please tell me whats up or what i'm supposed to do? Do i have to go back through the rooms and find a key to the front door, or what??? I succeeded in killing Elijah and even went back and tried locking him in, both with success, yet i still end up in the suit. The quest says escape the vault before your collar goes off, and i do. I just don't get it =C I am not sure what i have or have not done. I went through all the steps and such.

Wait, so you leave the Casino and you automatically end up in the Medical Villa?

no no ... when i'm leave the vault after killing Elijah/ trapping him *either way i do it* when i get to the exit of the vault, it send me back to the suit where Christine is. Where you access the elevator to the vault. Either way I go, killing him or trapping him in the vault, i end up back in the suit and Christine is still just saying " Good luck in the vault...ect., ect., ect. the quest is finished, just for the part about "escape the vault before your collar explodes" , but no matter which way i go *as in killing or trapping Elijah* , i still end up back in the suit.

OHHHHHH the "suite" not "suit". Ok well um, something is not triggering, once you reach either the elevator Ejilah comes from, or trek all the way back through where you came, you should hit a cutscene that brings you back to the Villa Fountain. You sure you're completing it right? Sounds like a trigger is not being hit, even though it should be triggering.

According to the quest itself, I am/have, but yea obviously i missed something. I just have no clue what. *sighs* well i'll go back to an earlier save i suppose, and try from there. Thank you for the responses, and help. *Hehe! Yea, suite, sorry about that =P *

You have to exit the suite via the hall elevator back down to the casino and then exit the casino via the door back to the villas. Sometimes that triggers the finish video.

Only problem is, when i get to the door *A.K.A the entry point for the casino itself, where you first start once you get into the casino* for the villas, its locked, and says "this lock requires a key, and cannot be picked", or something to that effect, hence why i asked in the original post if i had to go through the place again and find said key to escape.

I had that problem. I vaguely remember reading I should wait awhile and that the door would unlock. I do remember that it would not unlock, and after a reload, I went and saw it was still locked, but then a minute later it unlocked. don't know if that helps.

I believe your not exiting from the correct location... Pretty sure I had this happen to me once.
