City of Heroes has just released Super Booster: IV Martial Arts that will give players a stealthy new costume set, several new emotes, and ninja-style costume changing techniques. The new content is available on the NCsoft store for $9.99 and will unlock the content for all characters on your account, but players will need to unlock one additional costume slot to use the costume change emotes included in the new content by completing costume slot missions in the game.

Not only does Super Booster IV: Martial Arts offer you a stealthy new costume set, brazen emotes, and ninja-inspired costume change techniques, but you'll gain access to the exclusive Ninja Run travel power so you can dash through the city with the agility of a ninja! Use Ninja Run to strike fear in the hearts of your enemies as you increase your run speed and leaping abilities. What's the best part? It doesn't use one of your power selections!
