Requisition

A requisition (REQ) is a feature in Halo 5: Guardians that allows players to customize their experiences in Arena and Warzone multiplayer by offering cosmetic or in-game bonuses. Requisitions are unlocked by obtaining Requisition Packs, which can be earned through gameplay or purchased via microtransactions.

Unlimited-Use Requisitions
Unlimited-use requisitions are cosmetic items, such as weapon skins, armor permutations, or assassination animations. These requisitions can be used in both Arena and Warzone.

Single-Use Requisitions
Single-use requisitions are items that give in-game advantages, such as power weapons or vehicles. These cards can only be used in Warzone.

Each single-use requisition has a REQ level requirement that must be met before it can be used. A player's REQ level can be raised by killing AI bosses or other players. When used, single-use requisitions consume energy, which is earned automatically over time. Higher REQ levels allow players to hold more energy in reserve at once.

Obtaining Requisition Packs
Requisition Packs can be earned by ranking up in Spartan Rank or completing Commendations. Completing Arena or Warzone matches rewards Requisition Points, which can be used to purchase Requisition Packs. Requisition Packs can also be purchased with real money via microtransactions.
