Hey, Halo 3 was one of my favourite games growing up and I've had the urge to 100% it. I understand that there is currently an exp glitch that hasn't been resolved since September, but I was wondering if a bunch of people wanted to all boot up their 360s, grab a controller, and grind some multiplayer achievements. Not that many people play anymore so finding matches won't be an issue. Hopefully, the community cooperates.
