As part of its marketing efforts to promote the upcoming "Halo 5: Guardians," Microsoft will release a new content updated inspired by the popular sci-fi first-person shooter for "Minecraft."

The update, which will be released for free, will serve as an add-on for the "Minecraft: Halo Edition" mash-up pack, according to a report by the Xbox Wire.

The update will be available for the Xbox One and Xbox 360 versions of "Minecraft" and will feature new skins designed after characters from "Halo 5: Guardians." These include Master Chief and members of his Blue Team as well as Spartan Locke and his Fireteam Osiris.

Those who already have the "Minecraft: Halo Edition" mash-up pack can get the content update for free once it comes out on October 27. Those who still don't have the game can purchase it through the Xbox online store for $3.99.

The "Minecraft: Halo Edition" mash-up pack first came out in May last year for the Xbox 360 followed by Xbox One version in August.

As its name suggests, the pack features various elements from the "Halo" series such as 31 music tracks, themed menus and user interface, craft-able items and a textured set.

It also includes "Halo" world designed in the style of "Minecraft" such as Silent Cartographer, Sandtrap, Valhalla, Blackout, Guardian and Blood Gulch. It also features 41 character skins such as Cortana, Sergeant Johnson and the Arbiter.

Of course, since the "Halo" series is only available for the Xbox platforms, PlayStation owners should not expect to get receive the upcoming update for their console's "Minecraft" version. After all, the mash-up pack was only released for the Xbox One and Xbox 360.

As for the "Halo 5: Guardians," the game is scheduled to come out on October 27 exclusively for Microsoft's next-gen console. Recently, development studio 343 Industries released a blog post detailing the game's rules for its multiplayer or Arena mode.

One of the guidelines explained by the studio is the game's Competitive Skill Ranking (CSR), which is the system that determines a player's status based on his or her performance in matches.

"The Competitive Skill Rating system in 'Halo 5' is designed to ensure high quality matches between players of equal skill, on a per-playlist basis," 343 Industries wrote. "When you first hop into any Arena playlist, you will play a series of placement matches before earning your CSR."

"After you complete 10 games, you will be placed into one of 7 CSR ranks based on your performance," the studio continued.
