Another retro game in PS Plus Premium's classics range has received Trophy support. Herc's Adventures, the LucasArts PS1 action game, became part of the collection last year, but now has a selection of Trophies to collect.
The catch is that, currently, only the PS4 version has the list of gongs. Presumably, the PS5 version will also have an identical list in future, but at the time of writing, Herc's Adventures only has Trophies on Sony's last-gen console.
Of course, it's backwards compatible on PS5, so you can pop the Trophies on the modern machine anyway. The PS5 version of the game will get the list eventually, though, so if you'd rather have your Platinum come via that, you'll have to wait a little.
Herc's Adventures isn't the first classic game to get Trophies post-release; not too long ago, the same happened for Thrillville, so it seems efforts are being made to get these old games kitted out.
