News just broke on the PlayStation Blog that the UNCHARTED 2 multiplayer demo has officially ended and they’re unable to get it back online before UNCHARTED 2 goes on sale nationwide later tonight.

It’s already been reported that the PlayStation Blog was running a giveaway for the Fortune Hunter Editions, but in response to the demo ending, they’ve increased the winnings.

Asad Qizilbash, Marketing Manager for SCEA posted on the PlayStation Blog earlier tonight:

For Saturday and Sunday we’re going to increase the number of Fortune Hunter Edition prizes from 10 to 20 each day. For Monday, we’re going to honor the contest by drawing 10 winners from all those who logged on this morning.

For more information, head on over to the PlayStation Blog for the full announcement.

Good luck and good hunting!
