I think this movie may have been a Netflix original movie but not sure. These people are in this building and they are playing a virtual reality game when they realize its real and people are really dying. They are forced to continue to play if they want to live and they are going down the floors of the building to each new level. I can’t remember the name of this movie???
“The Call Up” (2016)
