Borderlands 2 on Vita will support cross-save capabilities with PS3, but that feature isn't live just yet. A patch to add cross-saves is heading to PS3 "shortly," a Gearbox representative said in the Borderlands 2 forums.
Borderlands 2 launched in a bundle with the new, slimmer Vita on May 6, and the standalone Vita game hits on May 13. The Vita game includes six DLC packs: Captain Scarlett and Her Pirate's Booty, Mr. Torgue's Campaign of Carnage, the Psycho and Mechromancer Character Classes, the Ultimate Vault Hunter's Upgrade Pack, and the Collector's Edition pack.
The Vita version of Borderlands 2 supports a maximum of two co-op players, though the SCEA Third Party Production team "strived to include four-player co-op," Sony said.
