dead_flag is initialized to 0 and is used to control whether the player is considered dead. When health (extra) is < 1, dead_flag is checked and then set to a random value. The value of dead_flag is then used to determine the angle of the player's view when dead. Note that up until EDuke32 1.4.0, it was possible for the random value of dead_flag to equal 0, effectively marking the player as alive again. This phenomenon occasionally resulted in the dead player's suicide counter being incremented in addition to a frag being awarded to the attacking player.
