505 Games has announced that the PS Vita version of Terraria has been officially approved for release by Sony. It's been a long time coming, but it's finally happening.
Those located in North America will be able to purchase the indie sandbox title on December 17, with those in Europe having it available to them a bit sooner on December 11. If you've been playing Terraria on PS3 lately, you'll have noticed the update that recently went out -- that update, 505 has explained, enabled Cross-Play compatibility with the Vita.
