If you reaaallly want them take a look a HForums (just google it) or ForumKorner. However, you're not coming away with a good one without spending atleast $250+ tbh.

Ice Challenge
Abductory
Arrile

If you know a person who has it on just use Horizon and Gamercard Viewer and put his name in and hover over the gamerpic to see where it from and then you can get it for free.

use horizon and click gamercard viewer and then hover over the gamerpic and it will tell you where its from and then just use the Gamer Pic Pack creator to get it for free from GPI or something.

I modded mine a while ago and I have around 30k... I sold my xbox now though.

I don't really see the point in going specifically for achievements though. It doesn't really get you anywhere.
Neithe ...

I recently made the gamertag 'Ice Challenge' due to the challenges going around. It's not OG but its very recognizable due to the recent exposure lol

Try the monster hunter frontier game 2 - day method I used that for about 7 months when they used to give 14 days, but IDK
if that still works for 2 - days.
