The problems that exist with Halo 3, and the countless other Xbox 360 games, are with Microsoft. They control the servers so it's up to them to work on a patch/fix. This is something that 343 Industries has little to no control over.they have control wym, 343 telling microsoft a bug exists is 99.99999% more likely to get it fixed than me going to support and telling them ( which i did 17 ish days ago)
came out on Xbox 360 over a decade ago. It's surprising that there haven't been more issues, to be honest. Fixing problems with the original Halo 3
, on Xbox 360 servers, its pretty close to the bottom on the priority list. However and whoever handles the issues, isn't going to bend over backwards to try and get this fixed. They have bigger fish to fry.
