The Korean Game Rating Board has a listing for a game our machine translation calls Bootcamp with a description that invokes Halo 3 (thanks Dave). Here's the translation: "Halo 3 first-person point of view of the world based on the contents of the Action Game software going to perform the mission expressed mild violence (third-person point of simple weapons, attack representation and fresh blood description) that the game industry, therefore Article 21 of the Act on the Promotion and classification hearing in accordance with paragraph 3 of Paragraph 9 2015 Rated PG 'classification as decided." Gamefront contacted Microsoft about this and found out this is actually a thing. Here's what they were told: "What’s Bootcamp? It is not related to our Xbox One efforts, or the Reclaimer Saga, but rather a project we’re very enthusiastic about and will have more to say about in the near future."
