The Game Guy
UPDATE (11:55): It seems the free "Uncharted 3" deal is no more. The game is now listed as "disc only" on Sony's marketplace. Multiplayer modes remain free to play. The deal was live and confirmed earlier this morning, but it seems it was an error.
Even though deal has been removed from the store, don't rule out "Uncharted 4" news next week at E3.
The original story on "Uncharted 3" being free for PSN users can be found below.
E3 2014 preparation is kicking into high gear this week, and Sony may be laying the groundwork for a major announcement at their upcoming press conference. Developer Naughty Dog’s critically acclaimed action/adventure title “Uncharted 3” has been made available as a free download to all PlayStation Network users. Formerly, only the game’s multiplayer modes were available for free.
