The collector's version of King of Tokyo: Dark Edition (see "'King of Tokyo: Dark Edition'") introduced a Wickedness Gauge, which is now receiving a micro-expansion of its own. This expansion allows players to add a Wickedness Gauge to any of the King of Tokyo games, and then gain Wickedness Points for various die rolls in-game. The points are tracked, and monsters gain access to different special tiles based on the points they accumulate. The mini-expansion comes with a Wickedness Gauge board, 10 Wickedness tiles, 15 Monster counters, and a rulebook.
Along with a base game, this mini-expansion supports two to six players, ages 8 and up, and plays in 30 minutes. It will retail for $9.99.
