The one where the clothes are unlocked has nothing to do with which assassin's dogma you played, but with the number of records of assassin's dogma series games in Uplay account (assassin's dogma 4 itself does not count).

1 Unlock Altair Clothing

Accumulate 2 pieces of unlocked Ezio clothes.

Accumulate 3 to unlock Connor clothes.

Login to Uplay official website, and see that my games include AC2(360 version), AC3(PC version) and AC4(PC version). I deducted 2 models from 4 generations and unlocked the clothes of Altair and Ezio.

Later, I uploaded the information of the fraternity (version 360) that UPLAY played but didn't record (logging in to UPLAY in the game will see the fraternity in my game, and the record will be uploaded after watching the progress, otherwise it will show 0%).

The fourth generation will have Connor's clothes, official Q &；; A mentioned that this verification response is a bit slow, and it may take 24 hours to finish, so an official told you to cut and reinstall the game (PC version) and he could watch it again directly. So the record is my game record in official website, not the game record of Uplay platform (Uplay platform only shows PC version). Anyone who bought a homemade series can add the game to Uplay to change clothes!
