Hopper mine

Hopper Mines are a type of explosive device used by Terrans. Possessing heuristic sensor links, they 'talk' to each other on a low-power network and 'learn' from each other what to look out for in an enemy passing over them. The more they detonate, the 'smarter' they get, even able to distinguish foes via their size and eveb whether they're dead or not (not detonating if that's the case).

The mines' blast pattern is set to maim rather than kill, but this can easily be adjusted through their programming.

Hopper Mines appear to function in the same way as Shape-charge mines although small differences likely exist.
