Having these titles available on PS4 is already incredibly exciting for us, but we did not stop there. We have brought these titles forward to meet today’s gaming standards by adding Trophy support! Each title’s Trophy set has been carefully developed in conjunction with feedback from the original creators to be sure that they capture the spirit and feeling of each game.
Also, you will be able to experience all of these PS2 games like never before — in up-rendered 1080p with the features you expect from a PS4 game including Remote Play, Live Broadcast, Share Play, Activity Feeds, and Second Screen support for game manuals with PlayStation Vita or PlayStation App.
And if you’re attending PlayStation Experience in San Francisco this weekend, you’ll be able to play these PS2 games on PS4 at the show floor:
