Jak and Daxter HD Collection: Jak 2-
In my session, I completed the Class 1 Race (netting a gold Trophy), explored the palace, destroyed the weapons lab (receiving a bronze) and defeating Krew (landing a silver).
I got the trophy for winning three straight online head-to-head games. So I just need to win two more games in a row, so I can get the five-win streak trophy. After that trophy, I should easily get this platinum.
