MotorStorm Arctic Edge

 is a racing game developed by Bigbig Studios and published by Sony Computer Entertainment in September 2009 in US and Europe and on 1 November 2009 in Japan for the Sony PSP. The game featured a single DLC for an additional vehicle, but with the shut down of the PSP frontend online shop it can no longer be obtained on the original console. 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).

How to obtain
The DLC 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 it on the handheld console.
