u need xbox live
The same way you would reach other ranks: play matchmaking, do daily challenges, and go for commendations
You play honestly. Play lots and finish daily challenges. Try the wiki as well. Maybe get the Halo reach guide book.
Each challenge has a time limit. You can check the remaining time of your challenges at www.bungie.net6:00am Eastern Standard Time
Easy ways to level up in Reach: 1) Do the Daily/Weekly challenges! 2) Anything "Firefight" 3) Action Sack 4) Living Dead
No, you mainly need a HDD ( Hard Drive ) for saving film clips and installing the game, which is optional.
By far, the best way to get credits are the challenges. Weekly ones give more of a reward, but for quick credits, do the daily ones. They can be seen by hitting the "Start" button, and scrolling down to challenges.
Simply you play the game, sir.Complete Daily Challenges and Commendation'sA little forewarning though, Do not by any means boost credits as it is bannable by Bungie.net
If you only have sliver membership, but you are still connected to Xbox live, you can do some of the challenges.
For me, what i did was i just spammed daily challenges and weekly and just did Firefight Arcade ALOT, but it payed off :D.
