PlayStation All-Stars: Battle Royale Vita is identical to its big brother, developer Bluepoint swears.
According to a developer post on the US PS Blog, Bluepoint vowed "to create the full PS3 experience of PlayStation All-Stars on PS Vita".
The Vita version incudes all the same features as the PS3 release - arcade mode, online modes, player progression system, unlockables and customization
"The connectivity and gameplay is a frame-perfect, seamless experience. The only separation between the versions is where players choose to play, not which platform," senior producer Daryl Allison said.
"Bringing the very best out of this portable platform has led our team at Bluepoint to hit back with a combo of high-end math and old-school dev tricks. It hasn’t been easy, but we’re doing it, and all with the game blazing at 60 frames per second."
Allison noted that graphics aren't enough; the gameplay has to be frame-by-frame identical for performance consistency across platforms.
"We regularly grab raw HD data and 240 FPS video to check that input latency, rendering fidelity and 'the awesome' remains tight. Running at 60 FPS is as much for the smoothness of the graphics as for the controls," he said.
"It’s important that there are no advantages (or disadvantages) due to the different hardware – no network lag, no input lag, so PlayStation All-Stars on PS Vita must be — and is — tuned to have the same tight gameplay responsiveness. From button press to character action, the quality of fighting is upheld to PS3 standards."
Regarding how the Vita and PS3 version interact, player progress is persistent across the two versions if they use the same PlayStation Network ID, and there's full Cross Play. Four Vita players can compete via a local Ad Hoc connection, or Vita players can battle against PS3 or other Vita players anywhere in the world over WiFi. You can also use your Vita as a controller to play a match locally with a PS3.
PlayStation All-Stars: Battle Royale will be free on Vita to those who purchase the PS3 version, and arrives on both systems in October.
