I believe at i33 they didnt use perks and everyone had basic weapons but im not to sure what they will do this time. Im lvl 52 btw ( Had to start again as i uninstalled and didnt save files )So i dont need to worry to much about leveling up.

My weapon sets are as follows:

1. AK-47
2. G3
3. M16
4. R-700
5. Mp5

I mostly have 3 frag, bullet penetration and stopping power with my sets. ( seems to Kill people quicker )
Close range and using assault weapons i am pretty decent with but my sniping aint what it used to be
