I am about to enter the kitchen to stop the gas leaks, but my collar is still beeping and blowing my head off. Where are the speakers to blow up. I have already shot one that was at the top of the stairs but i cant find any more active ones...

i actually had this exact same problem,what you will have to do is reload your last save before the kitchen and destroy the speaker thats right before the door that leads out to the top floor of the main room.

i did that but that one speaker i blew up didnt take care of all of the casino

Why is your avatar of a man with a shake wieght....seems kinda strange.

Because there is a radio in there......

There are radios and speakers at the other entrance to the kitchen too. In the bathrooms of the Cantina Madrid.
