Medal of Honor Heroes PSP download
World War II in easy to escape demo form
The PSP doesn't have a tremendous amount of first-person shooter games, let alone any with a half decent online mode. If you fancy having a go of one of the better examples of this under-represented genre on Sony's handheld, then look no further than this Medal of Honor Heroes playable demo.
To use this demo, create a new folder called ULED90008 on the GAME folder of your PSP and then copy the eboot.PBP file into it.
