You just click the left button like other guns, but the worst thing is it only has one bullet at a time except that it's powerful enough to destroy one crate with only one bullet.
However, it's not neccessarily the strongest gun. One bad thing about it is that you can't use ammo reducing perks, otherwise, Rosemary is unusable.
There are much better guns then Rosemary. One bullet deals only 10 points of damage, which is strange since in the newspaper, it took 1 shot to kill the demon, but 5 shots to beat the SMG-PK master.
If you want a better gun, I suggest going with the GAU-17 with exploding bullets on, or the M249 Saw if you need more control.
press shift and fire at the same time after you upgrade an assalt rifle to have a grenade launcher
To start, Uncharted is awesome you should get it. The best secondry weapon, i think is the the gun that fire srockets and the best fire arm is the AK47. I is probably the most useful gun in the whole game. But seriosly who cares what gun u use all u need to do is finish the game cause its awesome.
it is the strongest gun in the game but needs to charge
Reaching level 10 and using 10000 in game dollars, it is the GAU-17 Chain gun, there are no upgrades.
