Halo: Reach

EDIT: Thanks to TheDarKnyht for this information - "To everybody still hunting this achievement, Stockpile as of Oct 4th 2011 is back on the playlist for Team Objective. I managed to get this on the first try thanks to two people dropping from the other team."

This is much easier to do boosting, but all you have to do is collect all the flags on the map during one "round." Most maps have four flags, I believe. So basically, you have to capture the four flags at the same time. If you don't want to boost, get a good team together and communicate! You need people to get flags (I recommend two people working together, one to carry and one to defend) and people to defend flags once you get them back to your capture location. I suggest you place all the flags outside the capture location in case you do not get all four (or however many are on the map) before the countdown hits zero and starts over.

It is a team effort, so everyone can capture the flags. Once all four are capture, the entire team will unlock the achievement.

This achievement is NOT to capture all the flags that spawn on the map for the entire game of Stockpile (aka you do not need to win a game 10 to 0).

EDIT: According to TheDarKnyht, as of the October 2011 update Stockpile has been returned to the Team Objective Gametype and will now hopefully be easier. Good Luck! :)


This achievement was made difficult by Bungies removal of the stockpile playlist and the removal of the gametype, from DLC objective and team objective as well as flagstravaganza.

This gametype can only be found in Big Team Battle and Team SWAT (as of 8 July 2011) may change over time. This achievement CAN'T be unlocked in speedpile in action sack, it must be the original gametype.

You have to capture all the flags on the map at once, the capture zones reset every 60 seconds I believe so you need to bring all the flags into the circle within that time for them to all be captured at the same time. Any member of you team can bring them into the circle and the whole team will get the achievement.

To do Legit- Enter Big team Battle or Swat with a team or if you want to try and wing it. co-operate and keep all the flags near your base, steal if you have to form the other team's capture zone.

To boost- The stockpile gametype is very rare now. It only appears in Big Team Battle and Team SWAT. So to boost gather a team of 8 players (you can sign in guests, however they must get a few kills other wise you will banned for AFK boosting) play Team Swat and vote none of the above in an attempt to get SWAT STOCKPILE if you don't get it, play the game normally assuring all controllers get kills, then hope for it next voting round.
When you finally get SWAT Stockpile talk accross xbox live party to have one group run all the flags into their capture zone, other team does nothing. Flags capture then the other team moves all 4 flags into their zone and gets the achievement.

Goodluck,

I got this on Anchor 9.

The best strategy seems to be to grab the flags, DON'T drop them, wait near the score zone, close to the exit to space, until your team has 3 of the 4 flags.

As the map pack playlist is 6 a side, unless all 6 of the opposing players go for the one flag, your remaining 3 players should have no problem grabbing the last flag and getting it back to base, once the 4th flag is there, drop all 4 flags in the score zone, and defend the flags until the timer runs down.

If the opponent has any flags in their score zone, do nothing, wait for them to score and reset, grab the now returned flags and run, even if you lose the game, and only steal one flag per scoring window, you should get the achievement easily.

With the new playlists forn Oct 2011, boost in a party of 8 on Team Objective.

The STOCKPILE variant was quick to find and the boosting took five minutes.

FINALLY I have this pesky one checked off ;-)

[EDIT]:
You can use guest profiles - up to 3 gusts per XBOX. This helps making the boosting a lot easier. We did it with 5 live players and 3 guests.
Just be sure that if you wind up stuck playing some other team objective game before you get to STOCKPILE that you remember to use the guest controllers as often as you use you 'actual live' controller to avoid any banhammering.

As of 8-10-15 i unlocked this achievement on the "Team Objective" playlist. The achievement description is not clear on this but the goal is to capture 4 flags at once.By at once I mean 4 flags captured exactly at the same time when the countdown ends. I managed to unlock this in a regular non boosting game due to my good team mates and communication. It is best to do this boosting though. Either set up a session on TA or get some friends together who have extra controllers(best set up: 4 people, each with 2nd controller).YOU DO NOT HAVE TO OWN THE ACTUAL DLC. From what I've heard around it is possible to unlock all noble and defiant achievements EXCEPT the 13 point one for breakpoint(you have to have to dlc to play the breakpoint map).Also you MUST OWN Anniversary DLC to get their achievements. Below is a video guide of the achievement and it happens to be on the map I unlocked it on. Shout out to Filipe[pt] for the video.

I got this achievement while playing multi-flag in space station map on the defiant dlc. I was dead at the time. So, even though it say YOU have to get the flags, after getting the achievement it says that your TEAM needs to capture all the flags.
