This fall, 343 Industries is introducing a new way to unlock goods in Halo 5: Guardians multiplayer through the use of the game’s new REQ System. REQ Packs contain randomized rewards from three different categories: cosmetic, permanent, and single-use.

Only some REQ Packs — cosmetic ones, to be specific — can be used in Halo 5: Guardians’ 4v4 Arena Multiplayer. In Warzone, Halo 5’s 24-player plus AI multiplayer mode, nothing is off the table. Cosmetic, permanent, single-use packs can all be used.

343 says players will be able to purchase REQ Packs, but will still need to “level up and earn the right to use them, same as everyone else.”

Over 1,000 REQ Packs can be found at launch with hundreds more to come in the eight months following. To get a better picture of what Halo 5’s REQ System is all about, check out the humorous video above, featuring the one and only Mister Chief.

Halo 5: Guardians hits Xbox One on October 27.
