I hate that room so. bloody. much. Took me like an hour to get through it. Totally worth it though, have been using that outfit ever since I unlocked it.
Looks like Altair's outfit, but there are differences and for that reason I like Thomas de Carneillon's master assassin's outfit even more. They are similar because they are issued with in the same time period.
Yeah outfit is cool. I dont mind being a reskin cause never played AC 1. Wish it had gloves though.
