The Proximity Mine Mk.1 (or Prox Mine), is an explosive item that, when thrown (placed) on a surface will explode whenever an enemy is in range, killing them instantly. The Proximity Mine can be destroyed by any item that deals damage in the game (ie. Gun, grenade, Rocket Launcher, etc.). Prox mines cannot be destroyed by a member of the same team and will not explode when a member of the same team comes within range. Prox mines can be found by using the HRV. They beep and can be heard when not in range. When the player is in range the Prox mine will flash rapidly and make its beeping sound faster until it explodes. The player who placed the Prox mine will be credited for any deaths it causes.
