What is the SF movie that some strangers find themselve in a maze of collapsing rooms and only one survives?

It is part of military experiment and people try to solve some code of numbers and yet the number simply means the time left till the rooms dimensionally collapse. They die one by one, one by being sliced by some kind of futuristic-looking machine, another by stabbed by some others, etc. At the end, only one female escapes, who was actually military officer knowingly placed in the maze to collect data, but she also is killed upon presenting a disc to other waiting for her. It is at least several years old.
