SNK Playmore has unveiled a PSP shoot-'em-up called Neo Geo Heroes: Ultimate Shooter.
This will be available for Japan in June, but has no Western date.
Ultimate Shooter appears to be a sequel to King of Fighters shmup Sky Stage. 1UP said the game takes characters from SNK history and re-casts them in a scrolling shooter.
Familiar faces include Akari Ichijo (Last Blade), Marco Rossi (Metal Slug), Iroha (Samurai Shodown VI), Kyo Kusanagi (The King of Fighters), Iori Yagami (The King of Fighters), Terry Bogard (Fatal Fury), Mai Shiranui (Fatal Fury), Athena Asamiya (Psycho Soldier), Kula Diamond (The King of Fighters) and Dale Winton (Supermarket Sweep), probably.
Incidentally, KOF Sky Stage is due for release on Xbox Live Arcade this summer in Japan. A Western release hasn't been mentioned.
