The Korean Rating Board has accidentally leaked a new Halo-related project called Halo: Bootcamp. The listing seems to state that it has connections with Halo 3. However, we can confirm that this is unrelated to Halo 4 or the Xbox One. Microsoft released the following statement about the leak:
This is presumably related to Reed Ruiz's comic book Halo: Fall of Reach: Boot Camp, published by Marvel, which details the early days of Master Chief's military career. If not, this is a very strange choice of title. Perhaps this may even be a prequel to the Halo series where we find out more about how it all started. We'll keep you up to date on this story as it progresses.
