Halo Wars

The other solutions here suggesting that you can get it by being in the home page and such are completely false. You must be playing the game to get this achievement.

With that said... I was able to obtain all of the achievements within 21 hours other than the multiplayer ranked achievements and the 24 hour achievement (obviously), and so I had no more of the game to play. While this might not be the case for all, if you fall short, I have a definitive solution!

Go into the title screen, click on 'Tutorial' and load the 'Basic' tutorial. Once you're in, make sure the text in the top-left has gone through one cycle, that you have a plugged-in controller (or one that will last for at least 24 hours or the amount of time you need, I guess), and walk away.

NOTE: You have to exit the match in order to receive the achievement. With that said, you should try to figure out how much time you have left by waiting for the playtime statistic to slide along the ticker on the bottom. If you need proof that this method works, check your time, load it up for a few minutes, then go back and wait for the time stat to come back across.


I give you the Aero guarantee that this will pop using this method! Why the other guys couldn't come up with this, I don't know...

As always, if you have any questions, feel free to PM me.

You should not concern yourself with this achievement until you have beaten the campaign and played some skirmish and matchmaking.

Once you feel that you have played a fair amount of the game and you are at the point of "WHERE IS MY F*CKING ACHIEVEMENT?!?!?" wait at the main menu and pay attention to the text scrolling at the bottom keep watching until you see "Time spent in-game: __ hrs __ mins __ secs" then at least you know how much longer you have to play. So you can go get some other achievement to pass the time. (Note 1: achievement will unlock once the current mission or match is finished) (Note 2: This achievement only counts in-game time (or time spent actually PLAYING) so you cannot just be AFK for 24 hours) (Note 3: This is total time, so it does not have to be 24 hours straight)

What you can do is:

There are four achievements you can get while completing 24 Hours of Quality they are Playin' the field achievement [which is winning a skirmish battle with every leader].

My Virtual Friends Love Me achievement [win a 3v3 skirmish game with two computer allies].

In one of the matches and you are using a covenant leader[Arbiter, Brute Chieftain or prophet of Regret] you can get 2 Bugs are Better Than One achievement [win a skirmish game with two scarabs on the field].

The next one takes time, but that's what you want and that is Gallivant around the Galaxy achievement [win a game on every skirmish map].

If then you still don't have the 24 Hours of Quality achievement then play the campaign on a difficulty that you haven't started yet [easy, normal, heroic or legendary]. If you do all this you will get the achievement. You don't have too do all of it.

But I got 24 hours of quality after finishing those four achievements and finishing the campaign on easy.

Whilst following DealerDan's solution for "Epic Grinder", I believe I have found a method to boosting up your time a little faster.

I replayed Mission 12: Repairs, making sure to save the game just a fraction of a second before the "Mission Complete" text and score screen pops up. As per the guide, reloading the game here will continue to add the score earned onto your Lifetime Campaign Score - but I'm pretty sure it ALSO adds the time to your Total Time Played as well. I had made a note of my total time played before I started the solution of reloading my saves (22 hours, 5 minutes, 23 seconds) and within 45 minutes and a over a dozen or so reloads, "24 Hours of Quality" popped up. I thought I may have just got the achievement early somehow, but nope, the time scrolled across the bottom - Time played: 24 hours, 12 minutes, 29 seconds.

So, the SOLUTION: Play a chapter (preferably a long one) and make sure you save right before the "Mission Complete" text appears. Quit (B) to the Campaign Menu, load the save and repeat. Like I said, this will take less time if you play a long chapter, but any will do. If anybody else who is a few hours away from the achievement can confirm this, that would be awesome.
