New Halo 5: Guardians artwork has shown additional Spartans for the first time. Appearing to be split between the dominating figures of Master Chief and Spartan Locke it could suggest a split in loyalties between the Spartans when it relates to Master Chief and what he has done and will do. All is expected to be revealed when Halo 5: Guardians is confirmed to be getting a full reveal at E3 2015.
On the J!NX website which sells official Halo merchandise, pre-orders for Halo 5 characters including new Master Chief and Spartan Locke are taking place with additional Spartans still to be approved although Spartan Athlon is also available.
Halo 5: Guardians is exclusive to Xbox One and is available on the 27th October 2015.
