If you're a fan of light assault you might like this one. It's got some good spots and tricks that I use. I prefer the Laser Sight for this weapon over the forward grip. And you'll see why near the end of the video.
Nice video, man! How does the AF-19 Mercenary compare to the Razor GD-23 by the way? (Sorry, not too familiar with NC weaponry.)
OMG I just realized that Merc has less horizontal recoil than Razor. EDIT: Ugh, music at 1:38 destroys me. Overall gameplay is nice, gonna put that into my guide.
As a general overview, the Merc does better in close range while the Razor does better in long range. The razor has higher muzzle velocity and less damage drop off (maybe).
