Please bring back weekly challenges. I am a achievement hunter who is trying to get 100% on every halo game. You guys fixed Halo Reach A Storage Solution temporarily and I finally got 100% on the game so thank you. You guys have also fixed Halo Waypoint not working in late 2016 for Xbox 360. But come on now I can't even get 100% since the weekly challenges are gone. Thanks to cross platform sync i have the extra credit achievement on one platform but not on the other since the only way to get it is via weekly challenge. If you can fix halo reach you can fix spartan assault. Please 343, Im actually begging you to fix your game. I just want that 100%.
