You just build a things on a forge map the best forge map to do it on is forge world
because you need a 2 million credits to get it and do a lot of challenges
you go to firefight and put the invincibility on and go to school. when you come back you will have earned credits.
An easy way to get cR (Credits) in Halo Reach is to go on Multiplayer Matchmaking and choosing "Score Attack". You are the only one playing, and you get a lot of cR. You can also choose the maps and games to want to play on. Have fun with that.
a lot
Easy ways to level up in Reach: 1) Do the Daily/Weekly challenges! 2) Anything "Firefight" 3) Action Sack 4) Living Dead
A lot!
One way to view credit scores during gameplay (bottom right corner) is to select score while in the pre-game lobby and then select either free-for-all or team. This enables scoring during a game as if you were in a firefight game type.
You play a lot of multiplayer
Firefight Arcade awards a lot of credits. Each game on average awards 2,000 Cr and slot machines go up to 9,000 Cr if your lucky. The least amount of credits I got in a game was about 1,500
In my opinion, they're a lot longer than Halo 3's.
Probably ,because I played halo reach on a map that looked a lot similar to Blood Gulch , so probably.
In Halo 4 I've found that the gametype "Flood" gives a pretty good amount of credits (Somewhere around 2k) per game. I believe the "Grifball" gametype gives 3k.
