Solid Snake is coming to Rainbow Six Siege.

Not as a skin for an already-existing character, but a fully-fledged operator with his own unique loadout and play style. When GameSpot talked to Ubisoft Montreal about the future of Siege for our 10th anniversary documentary, we didn't quite imagine a crossover of this magnitude.

Although Ubisoft's Siege team has done crossovers in the past, this is the first time a character outside of Ubisoft's Tom Clancy universe has joined Team Rainbow. I sat down with key developers from Ubisoft and Konami to learn how a collaboration like this comes about and why Solid Snake is a perfect fit for Rainbow Six Siege.

David Hayter, the actor who originated the voice of Solid Snake in the Metal Gear Solid franchise, will reprise his role for the character's upcoming appearance in Rainbow Six Siege. Appropriately enough, Snake is arriving in the game just in time to come face-to-face with Zero aka Sam Fisher, the star of the Splinter Cell video games.

"For us, it was really a core objective to get Hayter for the English VO," creative director Joshua Mills told GameSpot. "Because it's just, again, very iconic, and we really wanted to be able to deliver that as far as the English VO."

Mills and content director Christopher Budgen confirmed that the team tried to incorporate Snake's signature cardboard box into the game. It just didn't quite work very well in the world of Rainbow Six Siege.
