The Chimeran Mine has many variations. The primary component is an artificial metal hole dug into the ground. This hole has motion sensors, so if an enemy moves too close, a small mine is released into the air, much like a Chimeran Hedgehog Grenade. However, the Chimera have seemed to abandon it's usage in favor of Drones. The mine variations are as followed:
The Laser Mine is not so much of a mine as it is a small auto turret. It fires an extremely long laser bolt, thus its namesake. It first appears in Resistance: Fall of Man and is seen again in Resistance: Retribution.
The Hedgehog Mine, simply put, is a Hedgehog Grenade with a much shorter detonation delay. It appears in Resistance: Fall of Man. For some reason, the Chimera have decided to stop using these mines earlier than the other variants, as it does not make a reappearance in Resistance: Retribution.
The Pulse Mine will either fly high releasing a horizontal shock wave to decapitate an intruder, or remain low to cut off the intruder's legs, making these the most dangerous mines encountered. It is first seen in Resistance: Fall of Man and reappears in Resistance: Retribution, except that the Chimera have redesigned the shock wave. It produces a spherical shock wave, but with a much shorter blast radius. The Cloven have created some of these mines to serve their own purposes. This mine was reverse engineered to create the Plasma Grenade.
