Johnny Impossible video review. Classic Game Room presents a CGR Undertow video review of Johnny Impossible, a downloadable game from UFO Interactive on the eShop for the Nintendo 3DS. Johnny Impossible is an old school 2D platformer, but the game is also quite current in its focus on stealth platforming. You play as Johnny, the titular character of UFO Interactive's Johnny games. You have to sneak through three different areas and accomplish a range of stealthy objectives. It's like Elevator Action meets Metal Gear meets Mario! This video review features video gameplay footage of Johnny Impossible for the Nintendo 3DS and audio commentary from Classic Game Room's Derek.
