I use the M4 for mid and long range and the USAS12 for close range. The M4 has a pretty nice range, lots of ammo, and burst fire (which either you hate or love).
Why use the USAS? It just has a habit of making people angry. The only time I would find it acceptable is if somebody had to take on many people at once, like in metro 64 man conquest.
But of course this is coming from somebody that's only been on the receiving end of this gun, so maybe I'm just missing something.
Boosting?Got 2000+ chopper kills since I started the thread and 400+ jet kills
Nope, just got a mate who I fly with. Mic + Good pilot/gunner + Caspian 64 = lots of kills, playing like any heli should
