Halo 5: Guardians is going to get a clan system, and 343 Industries has just announced that it's going to be called Spartan Companies. The multiplayer-focussed clan system will allow players to form up in groups up to 100-strong, creating unique companies with their own colours, emblems and banners. You'll even get a free REQ Pack containing a customisation item if you join or create a company. For more details on customisation, or to browse the companies that have already formed, head here. Halo 5: Guardians is heading to Xbox One on October 27.
