To put it simply a freeze ray.
Nature[]
Type 1[]
The more common type, this tech uses a low temperature compound and pressurized gas to expel a stream of the cold material onto a target. This device is the most complicated as it require acute timing in the fans and expulsion system as well
Type 2
This device is instead an EM that displaces the kinetic molecular energy of the target.
Appearance[]
Type one is almost always a gun of sorts while type two usually bears an antennae dish to emit their EM rays.
