Below is what you'll get when you cross-reference Ratchet & Clank with Vita on the ESRB website. I wonder what the holdup is with getting the Collection released in North America? Perhaps Sony are hoping to patch the first game, which I hear has some framerate problems on Vita.
Also in good Vita news, we already know that Rogue Legacy is dropping on the handheld on July 29th - yay! - but yesterday word dropped that the 2D action-RPG/beat 'em up Phantom Breaker: Battlegrounds will land on the handheld at the end of the month as well. Between this, Rogue Legacy and The Last of Us Remastered, July 29th is gonna' be a busy day for gaming!
Here, have some screens. Looks cool.
From what gameplay I've seen, Battlegrounds has an odd mechanic to it that confines heroes and enemies to single horizontal axis, and you (and they) have to manually switch from the path in the foreground to the path in the background - perhaps, essentially, eliminating those nasty Streets of Rage style moments where you're mashing the buttons and wiffing on an enemy standing just "below" you in a scene.
It's made by the folks behind the (little-known) Phantom Breaker fighting game and the Corpse Party series - so I'm hoping Battlegrounds will have some nicely deep mechanics to it.
