Ubisoft and Konami have had a collaborative partnership going on for a while now. Metal Gear Solid 4 featured an Altair costume for Old Snake to wear and in Peace Walker, Big Boss had in his arsenal a haystack cardboard box, perfect for those quick escapes and leaps of faith.
However, now its Ubisoft's turn to feature something Metal Gear related: Raiden's getting a neat cameo in Assassin's Creed: Brotherhood. Joystiq reports that the costume can be unlocked by completing every single task in the Animus' new "virtual training" mode. Playing as a cybernetic ninja during the Renaissance certainly sounds wicked, we can't wait.
Assassin's Creed: Brotherhood is out November 16 on the PlayStation 3 and Xbox 360. The PC version has been delayed until early next year.
