3DS Download Software

Sakura Samurai: Art of the Sword (Nintendo, $6.99) — It's like Punch-Out!!, only with swords instead of boxing gloves. It's a solid little game, as our Sakura Samura: Art of the Sword review explains.

DSiWare

GO Series: Undead Storm (Gamebridge, 200pts) — The GO Series returns in typically affordable fashion with a four player co-operative zombie shooter. We'll be fending off the undead apocalypse with a review soon.

WiiWare

Carmen Sandiego Adventures in Math: The Great Gateway Grab (The Learning Company, 600pts) — Any game where the official description starts with "breaking news from Mumbai!" has to be good, right? We expect this to be pretty similar to the previous Carmen Sandiego Adventures in Math games, but we'll still review it for you.

Nintendo Video

Drown in the Now by The Crystal Method (available 3rd February at 3 p.m. PST) — UVPHACTORY created a graphic black, white and red New York neighborhood that has been infested by small robots. The video culminates with Matisyahu's rescue via boat by The Crystal Method.
