Syphon Filter: Dark Mirror is considered the best game in the series, and for many people, it being on the PSP meant they never got a chance to play it, and a late port to PS2 was only for the hardcore. Fortunately, the game is coming to the PS Plus Deluxe tier soon. 

As spotted by Push Square, trophies for Syphon Filter: Dark Mirror has gone live on the PlayStation servers, so an announcement is likely imminent for the February PS Plus Extra/Deluxe games. For the trophy hunters like myself, the list is super-easy and will simply require you to finish the game to unlock the Platinum.

As a side note: there are two very good Syphon Filter games on the PSP, so hopefully, we get the Syphon Filter: Logan’s Shadow added to PS Plus with trophies as well in time, which was the last game in the series.
