If you want to get involved in the testing of Halo 3 on PC, all you need to do is sign up to the Halo Insider Program. The Halo Insider Program gives players the chance to take part in early access programs and provide feedback on how the games are coming along.

Once you’ve signed up – or if you’re already a Halo Insider – just make sure that your Halo Insider profile has an up-to-date and verified email, ensure you’ve ticked the box to let the devs contact you, double check you’ve opted in for PC flighting, and upload your latest DXDIAG. You can do all that by following the link here.

If you want to opt in for Xbox testing, simply follow the steps above and choose Xbox instead of PC. The steps are similar, but you’ll have to upload your Xbox specs instead.
