Core Reactor

The Core Reactor is a stationary robotic structure, which the Material Defender is required to destroy in each mine. The reactor stays dormant until an intruder is within its line of sight or fires a weapon directly on it. It will discharge beam projectiles straight at whatever is threatening it until the intruder is out of the same room as it. Because of its special characteristics, Homing Missiles and Smart Missile bomblets do not home in towards it. Upon its destruction a 50-second self destruction sequence will be activated causing the Exit Door and a few other specially locked doors to be opened. There is no in-game description of this robot.
