I'm curious, because I'm actually considering going after that annoying 50G and I want to get it before the end of '09, but I'm only at 11K, (LOL, KodaJay you noob! ....I know, feel free to laugh)
But, in all seriousness, what should I spend most of my time doing when playing this game?

BTW, if you were serious if/when you chose the last option, its an achievement for GoW2 worth 50G that is unlocked when you kill 100,000 enemies.

glitching it is the easiest lol, but if you want it legit its doing the brumak thing (only the beginning part over and over again...)

this

horde would be ok but it's more difficult then brumak and take a lot more time... brumak is like, one shot one kill.

brumak imo.

Don't be a pussy. Just work for it..

im making 1k per day

i think you got your answer? btw is that the only achievement you need? to have 100%

hordedoesnt get boring, brumak does

lol? horde was boring 5 waves in, killing drones over and over again is zzz...

Not quite, but I'm close.
