One eagle-eyed gamer may just have revealed the existence of multiplayer gameplay for Naughty Dog's highly-anticipated upcoming title Uncharted 2.
Kotaku earlier broke the news, along with a picture of a Best Buy placeholder box which clearly shows that copies of the superpowered open-world game inFamous will include a multiplayer beta voucher for Uncharted 2.
The voucher is listed as valid from 3 June 2009 through to 28 June 2009, which would most likely prove to be the dates for the beta.
While Sony has yet to officially confirm a multiplayer component for Uncharted 2, rumours of its inclusion popped up earlier in the week on ScrewAttack.
The site cited an anonymous source which specified that Uncharted 2 would pack co-op multiplayer; although this has been rumoured as being a separate mode from the single-player campaign, rather than allowing two player to progress through the campaign story. Competitive multiplayer modes were also rumoured to be included though no specifics on the game modes were given.
Internet buzz circulating the major sites indicates that Sony will be providing official comment on the story early next week, though now that the rumour is out there Sony might bring forward their announcement a little earlier.
