Free Games to Play At Home
To support Play At Home, PlayStation will try to make those occasionally dull moments more exciting by offering Uncharted: The Nathan Drake Collection and Journey available for free* for a limited time through digital downloads from April 15 at 8pm PDT (so April 16th Irish time) through May 5, 2020 at 8pm PDT (May 6th, 4am Irish time). Once you redeem the games, they are yours to keep.
For most of you, Uncharted: The Nathan Drake Collection will need no introduction. This three-game collection from the masters at Naughty Dog includes Uncharted: Drake’s Fortune, Uncharted 2: Among Thieves, and Uncharted 3: Drake’s Deception—all meticulously remastered for PS4. We can’t imagine a better time for globe-trotting adventures with Nathan Drake, an iconic cast of characters, and thrilling treasure-hunting action gameplay.
