I am debating if I should buy the Standard or Ultimate edition. Will the Berserker set be available to buy in the Helix store or do I have to buy the Ultimate edition?
My guess would be yes, altough I'm more inclined to say that you will (eventually) be able to buy it for Uplay points and not in the helix store.
The Berserker set would be in the Helix store not the Club.
