The "Halo 5: Guardians" Classic Helmet Req Pack, released by developer 343 Industries, features different helmets worn by Master Chief and others throughout the "Halo" history. From the fields of Harvest to the mountains of Reach, Spartans have constantly been at the front-lines fully clad in Mjolnir battle armor.

Players are to unlock nine legendary helmet designs from "Halo 3" and "Halo." Reach to customize your Spartan in Warzone, Warzone Firefight and Arena matches. Once unlocked, players can go to Spartan Customization and select any of the new/classic helmets.

Classic Helmet DLC Req Pack & Rarity Level

As reported by Microsoft, the following nine helmets are selected from 'Halo's" history. Included in the pack are Mark V Delta (Legendary), Military Police (Ultra Rare), Recon Gen 1 (Ultra Rare), EVA Gen 1 (Ultra Rare), Security Gen 1 (Rare), EOD (Rare), CQB (Rare), Pilot (Rare) and Operator Gen 1 (Rare).

There is a limited number of Permanent REQs available. If all have been unlocked, additional Single-Use REQs will be included. "Halo 5: Guardians" game and Xbox Live Gold membership (sold separately) is required.

Classic Helmet DLC Req Pack: Price & Availability

The Classic Helmet DLC Req Pack includes nine helmets and costs $10. The pack is the only option since the items are not sold separately. It doesn't look like it's already available just yet, although it should show up anytime now in "Halo 5" and through the game's Req Store at Halo Waypoint, writes Gamespot.

The Classic Helmet Req Pack is not the first piece of extra content that Microsoft has charged for, although all of "Halo 5" new maps and modes were free. In December, the company put out the Voices of War Pack also at $10, including new announcers for the game's multiple mode and a lot more. The next "Halo" game is "Halo Wars 2," which launches on February 21 for Xbox One and PC.

"Halo 5: Guardians" may be over a year old, but Microsoft is not through backing up the shooter just yet. Keep posted for more updates.
