PlayStation would like to remind you that various deals for upgrading PS3 games to PS4 are only available for a few more days.
The upgrade schemes allow those who previously purchased a PS3 copy of a game to snaffle the PS4 equivalent for a minimal fee.
You have until March 28 to take advantage of this for Battlefield 4, and until March 31 for Assassin’s Creed 4: Black Flag and Call of Duty: Ghosts.
It looks like Injustice: Gods Among Us is still good to go for some time yet, though, as no end date has been announced.
The PlayStation Blog has details on how to upgrade your games.
