-Ant- wrote Microsoft's code of conduct is very vague but I found this:

Dont make unauthorized modifications to your account profile or its contents.

Now, this would normally be used for modding avatar/gamerscore/gamertag etc.

But with the Gears 3 launcher you are injecting a downloader onto your xbox to start the download.

This may seem to have no relevance to your profile however the download will register to your profile and be in your download history which microsoft can see.

I don't personally know if they will ban, but you are certainly running a risk as with any modding.

So, basically there is a slim chance of being banned for "modding" onto your profile. But not really for playing it? Sorted.

Caboose123 wrote here's an easy idea...don't hop on the beta launcher. plus, the beta isn't live, so you can't even play it. just wait until it actually starts, which is in mid-April.

i only hoped on it once
ive get be more careful
dont wanna get banned
