Weapon Idea Thread

Hey guys! I was wondering if I could gather some suggestions for a weapon that I am going to add to my game. What I am creating is a Heavy Machinegun, but in addition to the normal "primary" fire, I also wanted to assign a "secondary" fire for the weapon to the right mouse button, which differs from the primary fire (like in Unreal Tournament). I am kinda stuck here, I had a few ideas but they aren't very interesting:

- A shotgun like blast (my initial idea, but we already have a pump action shotgun model - bummer)
- A plasma blast that can be charged
- The primary fire mode just more accurate with a slower rate of fire (although that would be 1:1 from Unreal Tournament)

Any suggestions, new ideas or just general opinions are welcome
