This plugin adds the ability for Claw Scanners to deploy Hopper Mines.
Pressing Crouch while a Synth Scanner will allow you to ready a mine, and puts you in the holding a mine animation, and pressing crouch again will drop the mine.
A mine can be readied every 20 Seconds.
Note: The Hopper Mine entities seem to be nonfunctional in clockwork at the moment. I'm not sure why this is, but it results in the mines dropped not exploding.
