A friend of mine, Curry UNSC is a Lt. Col. Grade 3. You can't go past it, but yeah, the last rank in the game is "Inheritor".

People have hacked infinite cR to show what is available to unlock (though obviously they can't use the hacked account on XBL).

Check out YouTube...

They have a level cap on right now so the boosters don't get too far ahead of the players who play all their games legit. Keep things on an even keel.

That's also why there's a daily cR cap.

what is the daily cr cap?

spend 3 hours on sword base and find out yourself.

get some customs going ourenggge.

yo scrub why u didn't accept my invite for reach?

full party probably.

my 360 scratched my disk so i couldnt load any campaign, firefight, firefight mm, and a couple of multiplayer maps. just buffed the scratches out for 20 mins, installed the game to my box. so doing campaign achievs atm.
