Stealth. Long has it been the bugbear of the Assassin's Creed series. The more swashbuckling, pirate-ship helm-ing and tree-climbing Ubisoft adds, the less they seem to mind that the stealth in their stealth game just isn't that fun. Might that change this time around? Maybe? Hmm.

IGN has posted a new walkthrough video in which game director Ashraf Ismail takes viewers through a number of stealth/assassination scenarios. They look great, as almost all pre-release Assassin's Creed stuff tends to. But they still do give me that familiar Assassin's Creed "stealth anxiety," where I watch the guy expertly climb onto a rooftop and dodge a guard's view and I can only think about how I'd totally screw it up.

Things I noticed in this video:

1) There's a shark! And Edward sneaks around it. Underwater shark-stealthing confirmed.

2) You can now tag enemies like in Splinter Cell or Ghost Recon, making it much easier to keep an eye on them through walls. That is promising. They're a crouch-button away from having a workable stealth game!

3) Edward appears to be able to push back his hood at will. GAME CHANGER.

4) The next-gen versions of this game will be pretty. But they'll also be pretty much the same games as the current-gen versions.

5) Havana looks a treat, and is the same kind of urban skate-park that Istanbul was in Revelations. Given that a lot of the Revelations people are making ACIV, that bodes well.

Okay, Assassin's Creed IV. I remain cautious, but some of this stuff looks awfully cool.
