The odd time-travelling affair between Kojima Productions near-future stealth franchise Metal Gear Solid and Ubisoft's historical assassination series continues as cybernetic ninja Raiden makes his Brotherhood debut.
Ubisoft has let slip that the star of MGS2 is offered as a secret unlockable skin once you've achieved a Bronze or better in all of Assassin's Creed: Brotherhood's Virtual Training Challenges. A nice little addition, and extra incentive to go back and beat those challenges.
It isn't the first time the two big-game names have touched base. Solid Snake could be seen creeping around the battlefield in MGS4 in an unlockable Altair costume if certain objectives were met.
