Early weapon damage chart showing actual damage values per bullet for each gun etc.
Looks like I thought it would unfortunately, with nowhere near the individuality of BC2's weapons. Very little balance either with the F2000 being outright better than the other AR's due to rate of fire advantage plus low recoil, and some guns just plain bottom of the barrel (the AK's due to slow rates of fire but no extra damage).
Poor show from Dice.
Edit: The AKS-74u does actually kill in one less bullet at range than the M4, but that still doesn't make up for the 150rpm slower rate of fire plus greater recoil. The AK-47M, AN94 and RPK are just blatantly underpowered compared to the other guns in their class.
Not sure about the SCAR. It's recoil is considerably greater than the other Engi guns so it does need to be more powerful. The PP2000 is terrible, should be 34 at point black range as should the UMP.
Hopefully they just didn't have time to fine tune and will do over the coming weeks.
