Super Stardust Portable

 is a shooter game developed by Housemarque and published by Sony Computer Entertainment on November 25, 2008 in Europe and on December 4, 2008 for the Sony PSP.

The game featured a single DLC that included new game modes and 2 new soundtracks. The PS Vita release of the PSP version allows to download the DLC, but to be able to get it on the original hardware a Sony PS3 is needed (see below for details). Unlike games, DLCs on Playstation 3 are region locked, meaning that PAL games are not compatible with the North American downloadable content.

How to obtain
The DLC can still be obtained on the PS Vita (PSP) release from the Playstation Store or, on the PSP, by purchasing the PSP version on a Playstation 3 system and then transferring the content on the handheld console.
