Each Division in WWII MP has progression system, reaching highest level of each Division unlocks unique weapon
Back at E3, Sledgehammer Games revealed that Call of Duty: WWII has 5 different Divisions, which replaces the create-a-class system. Divisions allows players to create their own solider, with each division offering unique set of Division Skills. Division Skill items can only be used in a certain division, but basic training items, which are perks’ replacement, can be used across the five divisions.
Alongside this, the GameInformer magazine has revealed that once you reach each Division’s highest rank, you unlock a unique weapon. The weapon itself can be used with any other Division. Weapons are not locked to a Division, but Division skills are.
Each Division also has its own unique set of gear items that will make players stand out in HQ. GameInformer says it will be easy to identify different players’ divisions just based upon the cosmetic items a player is wearing.
