Square Enix released a spiritual successor of sorts to Silpheed in the form of Project Sylpheed on the Xbox 360, but Gung Ho and Game Arts just published a new game as part of the Silpheed series for Android. You can grab Silpheed Alternative: Menace from Beyond the Stars on Android for $2.99. Here’s a trailer:
Silpheed Alternative begins with a civilian interplanetary liner being attacked by a fleet of unknown fighters. You can gain more powerful equipment throughout the course of the game, and missions range from protection of allied ships to destroying enemy flags.
