But there are a couple of problems with this masterpiece!
Blink Aiming! - ARRRGGHHH! Talk about fiddly. The number of times I have lost my stealthy intrusion due to the fact that the damned blink is refusing to show me the up arrow at my target that I just KNOW should let me up is beyond frustrating. Sometimes it appears and disappears so quickly that I know it is there but just can't get the damned thing to let me up... especially when I have a corpse over my shoulder. Other times it shows up and I blink only to find myself falling to my doom for some peculiar reason. Yet other times the arrows appear so far away from the top of the target that you wonder if it is truly the right location.
Lack of In-Game Stats - Why is it you only get your stats (how many kills, paintings, coins etc) at the end when you are leaving a damned mission. Most games that have stats like these let you view them in the actual level. To finish a level only to figure out you missed ONE painting is soooooo frustrating to a completionist gamer. Having to save just before you get on the boat with Samuel and then have to load up the next level before you can even load up the previous level save to go looking for the missing bits is irritating to say the least. Pleeeeease fix this.
Other than those two niggles I think that this is the game I have been waiting for.... waiting YEARS for. I hate games that have invisible walls that stop you doing a perfect flanking manoeuvre or let you choose your own path or solution. This game is a breath of fresh air (or more to the point, stinky, whale and fish smelling air).
So Arkane, awesome job guys. Now do some DLC missions... PLEASE! (maybe do one where you have to find out if the plague is actually a foreign power attack like the hints ingame... or is that coming anyway).
