Need some help with Pre-Sequel

I'm fighting the Sentinel inside the Vault, and I just keep getting my ass kicked. Could use some back-up. I've also been getting slaughtered by Odjurymir and would like to take him down before he goes away. If anyone sees this today (Sunday the 4th), send me a friend request (BrianS81177 on Xbox live) and I'll be on around 8pm pacific time.
