WipEout Pulse

 is a platform game developed by SCE Studio Liverpool and published by Sony Computer Entertainment Europe in December, 2007 in PAL regions and on February 12, 2008 in North America for the Sony PSP. The game featured 4 DLC packs,each one containing two new tracks and one ship. With the shut down of the PSP frontend online shop they can no longer be obtained on the original console. The PS Vita release of the PSP version allows to download all of the content, but to be able to get everything on the original hardware a Sony PS3 is needed (see below for details).

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