Close quarters weapons idea: Cryo-Cannon
I don't often try to come up with weapons because I usually find myself at a loss for ideas. But I really thought a flamethrower type weapon or similar would be fun. Some type of AOE weapon designed for sustained damage that performs best at close range and has no effect beyond mid-range. I'm also wanting for another weapon that applies a stasis effect. There's plenty of mechs that can do it already, but just 2 weapons. One of them is only accessible through referals, and isn't really relevant due to being low energy.
The weapon I had in mind is similar to the cryolator in fallout 4 but with a couple tweaks. They cryolator is something I consider a flamethrower variant, but instead of immolating enemies it freezes them. What the cryo-cannon does similar is spray a freezing mist with high fire rate and a low projectile speed. Where it differs is the width of the cone. The cryolator fires in a narrowish stream. What I had in mind for the cryo-cannon was a similar spread to shotguns, making it capable of applying stasis effect to multiple enemies at once.
The weapon would have low DPS relative to the shotgun. For example, it could have a magazine size of 40, a fire rate of 400 rpm, and reload speed of 6 seconds. An 8 energy variant would have a magazine total damage of 17,800 at 3 stars.
