This is a quite unusual gun pack. The box, which actually is the “Point Blank 2 + G-Con45” bundle, has a big sticker on it that covers its frontside saying: “G-Con45 + Ghoul Panic + Point Blank 2”. A barcode sticker covers the original one on the back of the box.
Except for the two games and the light gun, the bundle contains a Playstation “AV Adaptor” and some instruction leaflets. Both games are the multi-language variants, but only “Point Blank 2” has the “Not to be sold separately” text printed on the disc case back cover.
I think this pack is a Dutch exclusive release, at least I bought my copy in Amsterdam and have never heard of any other collector who have found this in another country.
