Not a clone by far.
Go rent it I guess, see for yourself.
As far as guns go..the close quarter loadout kills it and you start off with that available. You get the stauger at level 15 and when equipped with HH and reactive armor it's a legit weapon. Yes the higher guns like strata at 45 and masterton at 52 are best but ya know...earn them then like the rest of us and quit crying bout it. I used the first shotgun till I was level 40ish cuz it had quick. Reload and hold more. Learn how to be good and the guns don't matter so much. I gave a KDR on my level 52 account of 1.96 and a KDR on my level 14 account of 1.94. That right there tells ya you can be good no matter what gun you got. Kill the higher level players and take their guns!!! You can hang with anyone at any level if your any good.
