Steelbook here, exclusive edition there and pre-order bonuses everywhere. Looks like that those sleepers are slowly but still awakening in time, because Ubisoft SEA (South East Asia) has recently announced an(other) exclusive steelbook edition for (South East) Asian regions that seems to only contain the game, packaged in a unique special case.
Unfortunately we haven’t found a single place where it’s available to buy and the following video is the only information we have got about it.
For more information about the different pre-order bonuses as well as game editions, go to our overview page that explains all of them in detail.
