I don't think I've seen a game launch with so many ways of getting in game gear, pre-launch.
My list is...
Pre-order from Ubisoft - Free Secrets of the Pyramids quest, deluxe pack points and gear
Twitch Prime - Weapons, outfit and horse armour
Monster cans (through friendly folk in office) - 1000 drachmas, 3 weapons and crafting materials...with more to come
Amazon are offering a limited edition pre-order with shield and gear
Game are offering different pre-order gear
Anyone seen any other ways of getting in game goodies?
