Square Enix's Lord of Apocalypse will be our first example of a cross platform title that appears on both PlayStation Portable and PlayStation Vita. But it won't be our first example of a game that supports cross platform multiplayer between the two systems.
A follower of the Lord of Apocalypse official Twitter asked recently if the two versions will offer cross platform multiplayer play -- that is, will players of the Vita version be able to play with players of the PSP version. The response was no. The game only supports multiplayer with owners of the same version.
Lord of Apocalypse will be released on both PSP and PS Vita on the Vita's launch day, December 17.
