This is by far the easiest and fastest way of hitting max credit cap a day!
The challenge i was going for was to kill 400 enemies in any reach gametype. Campaign being the easiest. I went through and got 399 kills, saved and quit, then i chose the "Nightfall" mission because theres an elite you have to Ninja right at the start. Right as i assassinate the elite, and the challenge box pops up, i pull my ethernet cord out of my router (or anyother way you can use to disconnect from xbl) then save and quit. Connect back to xbox live, rinse and repeat!
Max credit cap is 60,000cr a day.
