The tracer is a modification for Quake made by Jonathan Avraham (also known as Procedure or Shambler). This gives the player a "tracer" that they can stick to Monsters or other opponents by using impulse 13. A tracer shot shall appear similar to a Vore projectile.
Note that each tracer shot shall require one Rocket and one Cell; the tracer will not fire if the player lacks said Ammo. After shot, the tracer will continually beep, which the player can use to evaluate distance. This can be used to determine if a player is moving towards them or is going to ambush them.
