By Stephany Nunneley

Killzone 2 went on sale in Japan yesterday, and so far the shooter has sold 20,000 copies.

Some retail outlets are reporting that the game is sold out and others claim supplies are dwindling.

The game’s on the fast track to outselling Resistance 2, another Sony exclusive, which burned through 33,000 during it’s opening week in Japan.
