As some have already noticed, Metal Gear Solid V: Ground Zeroes won’t have a platinum trophy. But this wasn’t a decision by Konami, but rather a result of Sony’s regulations. Kojima had this to say about it on Twitter:
The reason GZ doesn’t have Platinum Trophy in PS4 is due to SONY’s regulation. They won’t allow us to have them for non-full price game.
Metal Gear Solid V: Ground Zeroes will have 15 trophies in total – 13 bronze, one silver and one gold. For the full list, go here (may contain spoilers, so be warned).
