So, GamersBeverage has uploaded a video about the 3 previous game assassin's outfits and says that uplay detects if you have played any of the other AC games, if you have played AC1, you gain Altair's Not sure about Ezio's but most probably brotherhood as there are 3 games about him, and AC3's Connor outfit. This is cool, but what about the other people who haven't played the other AC games or do not own them and would still wish to achieve some of the outfits of previous outfits. However IMO I think these outfits are a bit useless as the default outfit is always best IMO. But I'm just saying for other people's sake.
It detected AC II, which had Altaìr in it. As well as AC: Revelations. So yea, there ya go. Explanations revealed.
Then I wonder how will it work in Poland - AC2 was not uplay enabled here (it had most of the rewards already unlocked, and it wouldn't give player any uplay points). I hope it will detect it though, just like acinitiates did.
