I haven't played this game in the longest, but from what I remember, playing that "horde" gametype gets you a ton of xp if your're good and fast.What's the fastest way to rank up? I started playing Sunday, and I'm currently a warrant officer grade 2. I want to get to General as fast as possible.
I'm pretty good. I get 20+ kills a game, and i win most of the time.
Better yet use that AIO tool atlas posted, good mods in there.
I'll be sure to make another build of it at some point. Usually Professional lets me know of a list of programs to add in.
