Requisition system

The Requisition system (REQ system) is a feature that allows players to unlock certain rewards which can alter cosmetics and gameplay within Halo 5: Guardians multiplayer. Players earn REQ Points after each match of Arena or Warzone multiplayer. These points can then be used to purchase REQ Packs, which contain various requisitions: unlockable weapons, vehicles, armors, skins, assassination animations, stances, and other items. REQ Packs are also earned by advancing to a higher Spartan Rank and completing Commendations. Although REQ Packs are earned in both Arena and Warzone multiplayer, only cosmetic items are usable in Arena to maintain balanced competitive play. Gameplay-affecting requisitions (such as weapons and vehicles) are, however, usable in Warzone. The requisitions available to the player are governed and balanced by Warzone's REQ Level and Energy systems, which are in turn dependent on player and team performance. New REQ content will continue to be released following the game's launch. REQ packs can also be purchased with real-world currency. The different tiers of packs include Bronze, Silver, Gold, and Premium with the level determining the quality of REQs inside. A Gold REQ Pack has a chance of including Legendary requisitions, while a Bronze REQ Pack does not.
