Hm, Was thinking of a "plasma reaper" so I decided to give it a go.
The view with the bullets below it, are the up/down views. The other views, are of the left/right. Wasn't sure how many the GANI would need, if it were to be added, so I left all the posibilites in there.

Name: Plasma Reapers
Type: Melee
Ammo: Plasma
Speed: (bullets would go same speed as r51)
______ (sword would cut at same speed as muramasa)
Damage: (bullets would do 15 dmg)
_______ (sword would do 37 dmg)
Clip: 15
Range: (bullets would go as far as reaper bullets go)
Description: Event Item.
Comments? :x
Single Handed:
Double Handed:
Forward 2 handed (just replaced them for rps, so not sure what they could do with it in GANI...if they couldn't do anything with them, then these are to big/bulky):

(That or they'd have to be 1 handed only, and held like a rifle)
