Uncharted 2. That's why, starting the weekend of May 28, the developer will launch a series of experimental online playlists every other week, as part of a promotion labeled "The Lab."
For instance, this coming weekend will see the temporary introduction of a 2 vs. 2 Team Deathmatch mode, in which pairs of players race to 25 kills. As an added bonus, this Memorial Day weekend will also earn players double cash, which should entice the prodigal treasure hunters among you to return to the fold. Check out Naughty Dog's naughty blog for more info on future experimental playlists.
