I got all the assignments relatively quick, really grinded hard and bang, got it within the first 4 days. Not all of them I have the last one, I don't really even want it though honestly dont we have enough shotguns?
After unlocking every weapon in bf3, surprisingly I have to say the an-94 is my fav. The burst is so great! smack a kobra scope on it easy 20 minimum kills per game! I hate it when players down guns when they just don't know how to use them.
When I first bought bf3, I ONLY played engineer, bad mistake... I got my g36 like 1500 kills around there, now that I reall started using the AN-94 its really close to overtaking it.
