Additional levels for the game can be downloaded from http://exitgame.us.ubi.com/ or http://exitgame.us.ubi.com/downloads/English.zip for a direct link. Additional language versions are also available from the game site.
With the PSP connected via USB you need to move the ten ULUS subfolders from within the English folder (found in the zip file) to the PSP under PSP\SAVEDATA\
For example:
PSP\SAVEDATA\ULUS10074DOWNLOAD01
It is also important that the ULUS folders are not renamed.
