These two clips suffer a bit from their conversion to embeddable Web formats, but that seems inevitable for something so quick and dynamic as Tatsunoko vs. Capcom footage. First, we have the commercial for the Japanese Wii release, narrated by Yatterman villains Boyacky and Tonzler.
After the break, we have extended gameplay footage, featuring a tag-team fight between Ryu and Street Fighter III's Alex vs. Ken the Eagle and Jun the Swan from Gatchaman. This amazing clip can be seen in higher quality at Famitsu. The super high speed and air combos help cement this game as a Vs. series game!
