on halo 3 for the sword attachment on the hayabusa which ones do you need?

ive read that you need to unlock all the achievments to get the sword on the back but they all said unlock them all which will give you 1000 gamerscore.

since you can now have a possible 1750 gamerscore for halo 3 which ones do i have to unlock or do i only need 1000 score? or do i have to unlock all of them till 1750?

You only need a 1000 GS. However, if it's not the original 1000, the katana can come and go. Get 1000 or just over it, and try to equip the katana. If it doesn't stay, you need to get another few points and then it will stick. I had 1005 GS and I had the option to equip but then it disappeared... got another achievement and it's been permanent since then. I have helped many people with the katana, so I know it works... good luck!

1000 gamer score plus 49 achievements its usually glitchy if you don't get the original 49 achievements

No, you only need the original 1000 score to get it at least thats how it worked for me.
