No, all achievements, items etc., are saved in their database even after the membership has ran out, simply obtain more and you'll get it back.
you have to complete halo 3 odst on legendary, have xbox live and complete halo 3 on legendary
You can't, but if you have internet and a free gold membership trial,you can use the trial to get the recon armor, it does work for Halo Reach too.
If you have an Xbox Live account, but simply choose not to sign in often then you can still use the armor codes to download the skins, and you can use the armor in custom games, but not in the single-player mode. If you do not have Xbox Live, then unfortunately the only way to get the armor would be by creating an Xbox Live account (it could be a free trial or a full account) and downloading the armor from there.
Only the color of the armor.
Halo Wars does have Xbox live.
By buying the limited edition Halo 4 Xbox 360

No, luckily. Those playing Halo: Reach without Xbox Live are not restrained by the level cap; meaning, you can skyrocket all the way up to the highest rank! Also, you can unlock all of the armor types. However, if you acquire Live after playing Halo offline, if you try to play online, your credit-earing rate will severely decrease, and you will lose all of your new armor online.
no you do not lose any achievements or data on halo 3 the only thing you need to change is when you get xbox live is your gamertag because millons of people play it and your current profile name would probly have been takenhowever your halo 3 data will not be lost
there are no cheats for xbox but you could download a mod for halo 3 to get all armour
Halo is only on the Xbox or the Xbox live.
you cant you can get more to get the locked armor by getting the new achivments and the mythic map pack. pop
