How do you get lot's of credits in Halo Reach?

Answer 1

The Spartan-Shooter Way:

Step One: Connect to Xbox LIVE (make a Gamertag if you're not yet)

Step Two: Try buying the Noble Map Pack, its playlist gives out decent cR.

Step Three (optional): Get some friends in a Halo: Reach party with you, to make Matchmaking more fun.

Step Four: Go onto Matchmaking, choose a fast-paced playlist like Team SWAT (Average is 7 minutes per match, you can earn from 700 to 1,500 cR) or a longer playlist like Noble Map Pack or Big Team Battle (the longer a match lasts, the higher your Game Completion bonus will be).

Step Five: Play some Halo! Just keep striving to be as good as you can and earn those cR the honest way!

Alternatively:

The Covenant-Crusher Way

Step One: Connect to Xbox LIVE.

Step Two: Go onto the Firefight Arcade or Score Attack playlists.

Step Three: Slaughter some Covvies. I reccomed Gruntpocalypse and 2X Score Attack on the Score Attack playlist and FRGfight and Rocketfight on the Firefight Arcade playlist.

Result: If you put in enough time and have enough skill, you should exit the battlefield with a few thousand more cR (depending on your rank, the lower you are the smaller you cR earned per match is). IF this doesn't help, go earn some Commendations (preferably without a Target Locator/Save Revert combo on Sword Base).

Now go and buy EVA [C] or something.

Answer 2

To get lots of credits play a lot especially firefight which gives out the most credits per game. Be sure to play well too to get a high commendation bonus. Also Bungie now states you get more credits when you complete all of your multiplayer games.
