Be creative here there are no wrong ideas.
I would like the Spartan laser to be a weapon personally, just called something different "Charge Rifle" was a name I had in mind

Did anyone play Phantasy Star Online? Well the robot race has access to these traps which would confuse, freeze and explode. So I'd like a gun that is completely for support, void type would put mobs in stasis, arc would shock mobs making them move and shoot erratically, solar would cause a small dot and stagger effect. Effect would last for 5 secs on normal mobs with the time decreasing as the mobs rank increases, and they would gain immunity after too many hits.
