When you reach the highest milestone does anything special happen, and what is the highest milestone number (IE 70 71…80)
I don’t think anything happens.
And I think its 70.
im on 70 right now, but i still have over half the halo wars achievements left to do, i saw somebody on friends list at 71 so i didnt know if 71 was the highest or if it was 72
The highest milestone is currently 75. Which I am, you must have all achievements in Halo Wars,ODST,H3,CEA, and Halo Reach.
> The highest milestone is currently 75. Which I am, you must have all achievements in Halo Wars,ODST,H3,CEA, and Halo Reach.
To add on, at 75, nothing happens, at all, no reward other than the ones you gained on the way to 75.
> The highest milestone is currently 75. Which I am, you must have all achievements in Halo Wars,ODST,H3,CEA, and Halo Reach.
Actually you can be missing up to 200 GS.

I am 75 and you do get a reward. You get 6480Cr added to your Reach Credits.
They have reduced MAX by 200GS

Do you really get cR? If so, I think you should get more than 6500. Earning all the Halo achievements is an amazing feat, and probably the most prestigious achievements.
Nothing, you get given an EVA avatar helmet but when you reach 70 all you get is the gamerscore and a lot of bragging rights.

That’s the one I need to have 100% I am almost a Brigadier
You get a sparkly sticker of Snickerdoodle riding a Unicorn…
My prized possession…
