Probably 90s, Action/Thriller

It’s one of those movies which a group of people stuck in somewhere, tries to escape and most of them dies. Only thing I remember about the movie is they had limited drinkable water and they were rationing it. A mouthful of water every day and they were fighting about it. I guess there was a guy looks like Samuel L. Jackson.

Not the 90’s but similar plot…

Fallout (1995)?
