Halo reach need easier ways to rank up

I have the problem to rank up in the Halo Reach campaign.

  • The CR for play time is 92 CR for 10 minutes and no time bonus for 10 minutes or above. - Commendations will only give CR after completion like Pinpoint from Silver to Gold. Commendations gives also CR when you progress until you reach Silver on the commendation. - The challenge payment is way to low. (Ex. 100 kills in any game mode gives 3000 CR and 180 kills in any game mode gives 2343 CR)

So go through multiplayer and grind it out that way. That’s how most of the Inheritors did it

play in anniversary gamemod, lots of people play it because they have halo1 anniversary, so they are quite noob, and sometimes i fell bad doing 30 kill whil they have 10, but in one game if you are good you can get a least 2500 cr.so farm the xp in this game mod(Watch out for other good player doing the same thing)
