I'm searching for a movie with like special forces that are doing training somewhere in a little dead town. One of them is the bad guy and I remember he kills the crew one by one with acid cigarette and liquid ice and at the end someone changes the time on the clock and puts glow powder stuff on it and finds out who the killer is. Anybody have a clue what this movie is called?

Mindhunters (http://www.imdb.com/title/tt0297284/)
