The PlayStation Network is about to get a whole lot indie-er this month with the upcoming release of three anticipated independently developed titles for the PlayStation 3.

On October 9th, VBlank Entertainment's crime drama parody Retro City Rampage will make its long-awaited debut for PlayStation 3 and PS Vita for $14.99. A PC version will also launch on the 9th via VBlank's website as a DRM-free download, with optional Steam and GOG keys. Releases for WiiWare and Xbox Live Arcade will follow later this year.

Also arriving on the 9th is Amanita Design's acclaimed adventure game Machinarium, which will premiere as a downloadable PlayStation 3 title for $9.99. A PS Vita version is also in development, but Amanita tells Joystiq that it "no idea when it will be released."

Finally, Giant Sparrow's first-person puzzler The Unfinished Swan will make its PlayStation 3 debut on October 16th exclusively for PlayStation Plus subscribers. A widespread release for all PlayStation Network members will follow on October 23rd. The Unfinished Swan will be priced at $14.99.
