The downloadable add-on for Uncharted 2 revealed by Sony Japan last week has been confirmed for worldwide release, although it's not free as was originally reported.
It will, however, feature the skins based on characters from Sony stable-mates Killzone 2, Resistance 2 and InFamous for use in multiplayer that we saw in those screens.
The PlayStation Heroes Skin Pack will be released alongside a demo of the game in this week's PSN updated on Thursday, 28th January. It will cost $4.99 / £3.99 / 4.99, according to the PlayStation blog. It contains seven skins: good Cole, evil Cole and Zeke from inFamous, Sgt Nathan Hale or a Chimera Hybrid from Resistance, and a Helghast Trooper and Tomas Sevchenko from Killzone 2.
There's no word on the other updates mentioned by Sony Japan - reportedly maps and skins adapted from Uncharted 1 due on 25th February, and a co-op mode with new maps and skins on 15th April. Naughty Dog did say that some of the news was "inaccurate" when it was reported on Friday.
