Microsoft and 343 Industries have announced how the Halo 5: Guardians requisition (req) system will impact both the Warzone and Arena multiplayer modes. They come in permanent and consumable varieties, and you can either purchase packs of them with earned req points or with real money.
The video below details the ins and outs of the system and how you can get cards. It isn’t specific about real money costs, but 343 suggests it is “generous” with doling out points to spend on packs.

Customization items are unlocked permanently and can be used in both Warzone and Arena. These come in the form of armor, helmets, assassination animations, visor colors, weapon skins, stances, and emblems.
Consumable items are only usable in Warzone. Using the MOBA-like in-match leveling system, you’ll have to reach a certain threshold and spend related energy to cash in a card for a power weapon or vehicle.
