I considered that, but you only really get two shots out of it, one from an internal tank and a second from an optional external tank, but the tanks are heavy and bulky along with the weapon being quite heavy and bulky. I figured it'd be super impractical as an actual weapon but useful in specialised situations, such as ship breaching. Plus it'll break down after a few shots due to the heat damaging the tool itself.
I'll need to come up with some way of limiting it's lethality a little bit more though, just anything that's firing plasma is going to be hot as fuck.
