Nope! They are dressed as Nintendo characters, though. Koei Tecmo is putting iconic outfits in the latest hack-and-slash Dynasty Warriors game, Dynasty Warriors VS, as unlockable items.
To be fair, only the costumes will appear in the Nintendo 3DS game, but look at that sample characters model Koei Tecmo released? Link gone all Dynasty Warriors. No thank you!
Samus Aran of Nintendo's Metroid fame is also lending her Zero Suit to the game. Koei Tecmo's Team Ninja studio made a Metroid game, Metroid: The Other M—a very good game.
