To
download a map enter Google Maps, hit the «Menu» button in the search bar, select «Offline areas» and either choose a preset map, like «Home» or select your own area to download.
Whenever I'm trying to
enter an Intercept game, I'm being told to go to the PS Store and
download the
maps to play (but I already have them
downloaded and installed / also running the latest firmware update and latest killzone patch and I have the Season's Pass).
