After much testing, Pinnacle announced in May 2015 that they were changing the way “Shaken” works. In the original Savage Worlds Deluxe rules (as well as earlier editions of the game), a Shaken character who made a successful recovery roll could only act on her turn if she’d gotten a raise on the roll.
With the rule revision (detailed in Savage Worlds FAQ and Update May 2015) this is no longer the case; a simple success is enough to act on your turn.
