Fruit Ninja might not really need updating - it's pretty feature-complete if there is fruit for you to slice, and you can slice it - but Halfbrick is adding content to the mobile game anyway in honor of its two-year anniversary. The new update will be live May 24.

Gutsu and Truffles join the cast (in other words, Sensei), bringing with them a shop where you can purchase powerups that add time, deflect bombs, or explode, in exchange for Starfruit, a new currency that you earn in-game.

Speaking of currency, Halfbrick is handing out the iPhone game at no cost right now on its anniversary website. The offer is limited, but we'd be surprised if this Starfruit update weren't leading into an optional microtransaction-based system like that in Jetpack Joyride.
