The overall compilation is dubbed the "SEGA Vintage Collection 2." Oddly, the announcement stated that the collection would hit both PS3 and Xbox 360 this summer, though listings only show Gunstar Heroes hitting both. Details and screens follow:

Gunstar Heroes (XBLA & PSN) - Summer 2009 / Online Play "The classic side scrolling shooter from the SEGA Genesis returns to captivate fans new and old with its non-stop action and cooperative play."

Altered Beast (XBLA) - Summer 2009 / Online Play "'Rise from your Grave' as the original Genesis launch game is reborn and comes to a new generation of gamers. Battle hordes of undead warriors and monsters as you return to battle in order to save Zeus' daughter Athena."

Shinobi (arcade) (XBLA) - Summer 2009 / No Online "Battle your way through the 'Ring of Five' as you save hostages with your ninja abilities."

Comix Zone (XBLA) - Summer 2009 / No Online "The game features an innovative art style that transports players directly into the panels of a comic as they fight their way to save a world from destruction as Sketch Turner. Everything from the speech bubble text, level design, and the revolutionary graphics scream COMIX!"

Phantasy Star 2 (XBLA) - Summer 2009 / No Online "SEGA's classic RPG which expanded on the success of the first with its epic storyline and battle system."

Sonic the Hedgehog 3 (XBLA) - Summer 2009 / Online Play "The game that introduced Knuckles the Echidna comes to a new generation of gamers as Sonic explores Angel Island and discovers the true power of the Master Emerald.

Sonic and Knuckles (XBLA) - Late Summer 2009 / Online Play "Picking up where Sonic the Hedgehog 3 left off, players can now play as Knuckles for the first time. In addition, if players already have Sonic the Hedgehog 3 or Sonic 2 in their library, they will be able to access the lock-on bonus content for each game for the very first time since the days of the SEGA GENESIS! This allows for gamers to play Sonic 2 & 3 as Knuckles!"
