Splinter Cell: Blacklist will hit store shelves in the UK on March 29th, 2013, according to a pre-order listing on Amazon UK. Games are generally released on the Tuesday before in the US, which means the game should be available on March 26th.
Both the US and UK listings for the game have leaked the game's box art, as well.
Just unveiled last month at E3, Blacklist officially has a vague "2013" release window. The game will bring many of series' action-oriented mechanics from 2010's Splinter Cell: Conviction, though the developers say old-school Splinter Cell players will be able to handle situations more stealthily, if they prefer.
The listing also reveals a bevy of pre-order bonuses for Blacklist. Joining Fourth Echelon early will net you the "upper echelon" suit, five pieces of armor that add "unique" visual and damage protection bonuses, a gold filter for FIsher's goggles, an "A2" poster, an art "leaflet and a downloadable mission. Plus, all of it comes in a steel version of the game's case, similar to the one Ubisoft is giving away for Assassin's Creed III.
Since the pre-order bonuses are only on the UK listing, it's unclear whether any of these items will be available in the US.
