The wraith and Shadow's Sub Machine Guns are a tad bit OP, I mean, I'm coming at them with full on Assault Rifles and they take me down, not sure about you but that seems a bit out of order.
Epic Game! Amazing Graphics, Nice Gameplay, all around a great game!
One think I might suggest is or an update host like weekly tournaments or something where the prize is Ballistic Points!
Get rid of VIP, it makes people OP, and people who don't waste their money on virtual goods get owned. That or either make VIP Packs unlockable like masters pack available after like level 30 or something
