Alright, it's not catchy, but it is a decent second batch for the 12 Deals of Christmas. The PS Europe promo runs until Christmas Day, with today's deals available until December 5.
A word of caution on Spelunky: The game should feature cross-buy, meaning a purchase of the Vita version unlocks the PS3 version. That said, the PlayStation Blog's deal specifically marks out Vita, and on the PlayStation Store the offer is only for the Vita version. We've reached out to Sony to confirm and clarify what today's discount specifically applies to.
Update: A SCEE representative confirmed to Joystiq the discounted Vita version of Spelunky features cross-buy, so if you buy it you'll unlock the PS3 version too.
