Uncharted 3 multiplayer is free to download and play from tomorrow, Naughty Dog has announced.

Gamers will be able to play up to level 15 free of charge in competitive online multiplayer.

Microtransactions will also be available to unlock the level cap, split screen mode, co-op modes, skins, and so forth. Pricing for these things is still to be confirmed.

We're sure this has nothing to do with the rather excellent Tomb Raider coming out next week.

In related news, patch 1.17 was released for Uncharted 3 recently, which added a platinum level tier to the multiplayer tournament mode, among other things.
