I just do Gruntpocalypse whenever I want to farm for some credits.  Even then, I've only farmed whenever there's a piece of gear that I really want to get. 
 
Knowing this, I might try it once, but not really interested in farming.  I played WoW for three years, and let me tell ya - after you've farmed enough Primal Fires and Primal Airs to buy epic flying long before they reduced the price...and on a PvP server nonetheless in an incredibly hostile place (that would be Elemental Plateau)... 
 
Suffice it to say, I don't want to ever hardcore farm anything again.

I'll pass. Bungie said they have a cap on points you can get daily and if they catch people manipulating credits then they will ban you from matchmaking.

well I had no idea that there was a way to credit farm but now that you said this, I might have to check it out. Its not cheating if its in the game

This exploit only works for about 40k credits. After that you get diminishing returns. You can keep grinding for the commendations by reloading but there are more efficient methods. 
Bungie will not ban you for reloading a checkpoint.

" I personaly don't like the fact that this can be done. I used to look at someone who is already a lieutenant colonel and say "Wow, that guy is a raving lunitic who hasn't put the game down since he bought it". Now i'm just "Ohh, he did the thing. What a dick". You should have to earn your credits with hard work and determination. "

 "Bungie will not ban you for reloading a checkpoint. "

Another method that works for a little while is to replay a mission on heroic or legendary (Winter Contingency is a good choice) with scoring turned on. Save and quit the game during the outro cinematic (as soon as it starts). Then you can resume the game from the menu and you will get 200 credits for every reload.

Yeah, they won't ban you for using credit exploits. Straight from the weekly update: 
Will I be banned for playing <my favorite gametype>?
Nope. You won’t be banned for legitimately playing Reach. If you find some particularly fast way of earning Credits because you want to be the first person on the planet with thunder and lightning swirling your visage, we won’t ban you for that, either. Assuming you’re actually playing, your efficient means of farming Credits will only expedite your trip to the Daily Cap – it won’t send you to Banadu.     
 
But yeah, I would only keep replaying that checkpoint for as long as it takes me to get the two corpses in one grave achievement.

Eventually it stops giving you as many credits... and even with the exploit, those ranks still seem so far away. I rather just play games when I went and get there eventually.

" @natetodamax: Weird could have sworn I saw something about that. Must have misread it. Well I do know for sure that there are daily caps. "

So, all you get is some skull things. You do not gain anything over other people. Let them waste their time leveling up for nothing if it makes them happy.

I want Birthday Party or whatever, so I might do this. Also need Two Corpses in one Grave achievement

Eh. It doesn't really matter. It doesn't affect anything in game...

" For those of you that don't know there is an exploit in Reach for getting lots of credits. There is a check point in the campaign right when you get the target designater that if reloaded over and over again will allow you to rack up kills getting thousands of credits in comendations.  Do you think this is cheating? Do you do it? Will you do it?  "

" @flufflogic: That stops being effective very quickly. "

If most Halo players are like me, you grind and grind, play match after match, and at a point you get sick of the slow progession. The campaign checkpoint farming only works for awhile. ou'll get a good 10,000- 15,000 CR, then it stops being worth the time. Once you've maxed on a few select commendations, you get very few CR doing the exploit, maing it a waste of time. 
 
Bungie has come out and said they have no problem with people milking their favorite mode (Score Attack) or checkpoint (ONI). They placed the 60,000 CR daily limit to prevent people from taking advantage of the system. If they're cool with it, I'm cool with it.

Bungie should give floating halo rings over your Spartans head if you didn't... wait.

I did the oni sword base thing a few times because it was fun.  It helped me get half way to getting warrant officer grade 3.  The points dropped off real fast.  Will they go back up after some time has passed?

If someone wants to earn the credits popping heads in gruntpocalypse that's up to them, they'll get merked online.

I'm not too fond of the credit farming since I end up getting bored pretty easily.  I may try out gruntpocalypse a bit though.   Leveling up does take a while, but I imagine it's suppose to. 

Is there some setting that you need to change in gruntpocalypse to get a high credit total?  I played through it and only got a little over 400 credits.  This was after I ran the oni sword base a few times.  maybe this had something to do with it.  like maybe I hit the credit cap for the day or something.  I just dont know why people are mentioning the gruntapcoc as a credit farm thing, you get just as many points and spend as much time as you would just playing multiplayer online.

You need to be chaining headshots and multi kills for gruntpocalypse to give any serious amount of credits, the oni checkpoint is way better for farming

What if they don't want to play online? Aren't they entitled to earn the rewards and play the game they just paid $60 for? "

There is a way to reset daily challenges. But that is considered illegitimate and you might have your cr reset.

People are free to waste their lives.

I'll admit I did this the day I found out about it. Had some fun blowing some dudes up for about an hour, Onyxed the Splash Damage Commendation, got bored and played some Matchmaking, only to find I hit the credit limit. So I stopped campaign farming. I'll play a good bit of Gruntpocalypse, but now that Bungie is lowering the credits earned in that mode to match the rest of the game modes, there won't be much use of playing it except for daily challenges.  
 
To those who are skeptical about farming credits, Bungie won't credit ban you for playing campaign or Firefight and legitimately earning credits. They knew this would happen, which is why they put in the daily cap. However, if you farm Challenges by disconnecting from Xbox LIVE, that's cheating, and you'll be very upset you did it.

To all those that did the Challenge farming, have fun getting all your credits you spent so much time farming back. :D

It only really lets you get like 40,000 credits before its useless. I did it and it took about 45 minutes before i was getting nothing out of it. Not im back to getting like 500 credits per mp match. I do wish there was a way to get more besides gruntpocalypse.
