Walking along, standing, and all of a sudden, no sounds or anything, black screen says "You are Dead". This has happened to me twice, once inside an industrial building, no way to be sniped, and once inside a fire station, just messing around a walking straight into a wall in first person inside the tower. This has also happened to my friend a few times, for example he was running down the street with his other friend and he died for no reason. The other friends did not hear any shots or any sign of it being a murder. The other time he was inside a building in a room with no windows.
