some suggestions for ac(graphic and gameplay)

[Cemer]

Not a one shot kill, maybe a small nade type thing. Would help in support situations.

one shot kill, this would be the unique feature of this weapon, a direct hit = kill, like a soldat's rocket launcher, the gun do a little splash damage, but, kill in a direct hit, it is possible to dodge the projectile in certain situations.

shotgun an sniper kill in one shot, but, in certains situations(head shot and close range), about rocket launcher, kill in a direct hit

Oh jeez. I misinterpreted it XD Sorry.
But if the rockets big, it'll hit easily, so it'll noob it up. :P
So a small direct hit zone.

Slow moving, maybe slightly lower than the grenades speed .
