You should really take a nice, long break from the DLC and either play something else or do something else. Go back to it when you're zen.
I don't know if there's a PC cheat, but I'd bet real money that there isn't one for consoles.
Exactly where are you stuck? Did you just enter the "vault area" (radios, turrets, holograms, and the Vault proper), or did you enter The Vault proper (gold, armor, computers)? Are you somewhere else? Maybe we can help you through it...?
*Sigh*
I am stuck say 10 meters in after the elevator, at the point where you start having to run and jump while the collar is beeping. I looked for speakers but I just cant see them from the door and spot them on the run? I started but I am sick and tired of the death animation. In 100 hrs of gaming I died like 4-5 times, and I learnt from every single death, like "ok thats how a powder charge looks like. Now I know, wont happen again." (Ok so it DID happen again but at least I just got crippled)
There is nothing to learn here just repetition "Is the speaker here? No. Boom. OK I try over there... Boom."
Up till now I could back off , look and think. "Hmm the border of the speaker goes here.. aha!" But all to often I had rush in and look for it. Not my style.
Thanks for the offer but I dont think any advice in the world can give me faster reflexes.
Reflexes wich, I migth add , isnt required in the "base-game", thou I am sure it helps or alow (?) yet another play-style,, wich is nice
Yeah you are rigth a break is in order.
