There are many ways to earn the commendations. You can earn them from campaign missions(low amounts rewarded),matchmaking matches, and I'm not so sure about firefight. The better of them is matchmaking. My favorite way is to go to the matchmaking gametype select menu, hit select firefight, and then select score attack. You may want to select grunt-apocalypse for the easiest and quickest commendation earning. That's about it.
P.S. If you don't have Xbox Live, your pretty much screwed. But you can try going to the spaceship mission on the campaign and do it repeatedly on heroic difficutly or higher.
Drast
yes but you can play matchmakeing firefight on your own
none they all reqire xbox live
The same way you would reach other ranks: play matchmaking, do daily challenges, and go for commendations
You get credits for finishing a game, wining a game. and getting commendations.
yes. most commendations require Xbox live, because many are matchmaking or require matchmaking firefight, where you need to have xbox live to connect to.
complete challenges or commendations
Halo reach is older
The best gamemode to play is score attack gruntpocalypse, you get over 1000 exp a game, a game averages around 7 minutes, and you get commendations along the way. Works fast for me!
no, Masterchief is not in Halo: Reach. Halo: Reach is set before the discovery of Halo, if you have or Know about the Halo book: The Fall of Reach, it is a closer view of the plant reach. but there are some other Spartans in it!
