Kinetic Mine

The Kinetic Mine is a new item introduced in the Unto the Evil DLC. It is a mine that leaps out and explodes on the victim when in proximity to it, dealing 130 damage. It can be detonated with weapons fire, even after it has detected a target. It's a multiplayer-only equipment item, and recharges after use.

Trivia

 * Kinetic means moving or resulting in motion which means that this mine can most likely detect kinetic energy, which is how it knows someone has passed, which it then targets, hops off, and explodes.
