In this expansion, the Mindbugs have taken a portal into Tokyo to do battle with the various Kaiju monsters plaguing the city. This Mindbug game, designed by Skaff Elias, Richard Garfield, Marvin Hegen and Christian Kudahl, features King of Tokyo-like mechanics in a card battler game, and adds a special die to trigger crazy attack effects. It is playable as a standalone or with other Mindbug sets (see "'Mindbug' to North America").

This game is for two players, ages 8 and up, and plays in 15 to 25 minutes. It will retail for $29.99.
