Naughty Dog's planning to do something multiplay-wise in Uncharted 2 this week, as tweeted here.
"Things are looking up that we're going to have something quite awesome lined up for multiplayer at the end of this week," said the dev.
"Quite" awesome? That's a bit rubbish. Shouldn't it be "AMAZINGLY AWESOME"? Sort it out, Naughty Dog.
No, we've no idea what it is.
