Celebrate HWC with free Halo 5 REQ DLC and sneak peek at Warzone Firefight

It's a good day to be a Halo fan.

Halo 5: Guardians owners can grab a free REQ pack DLC in celebration of the Halo World Championship finals today.

The pack includes the Challenger armour set and HaloWC emblem. Grab it via your Xbox One or the web store.

The tournament has clearly left 343 Industries in a benevolent mood. In addition to handing out free goodies, the developer produced a new trailer giving us a look at Warzone Firefight, a new co-op mode it began teasing in February. Viddy below.
