I doubt there are any PlayStation 3 owners who are not aware already, but the demo for Killzone 2, one of the most anticipated PS3 games this year is up and running and can be downloaded right away. The Killzone 2 demo was released yesterday in Europe only and the number of European users on the PSN probably skyrocketed (since PS3 owners from all over the world created fake accounts to get the game).
The Killzone 2 demo delivers the full game tutorial and the first two stages of the first level, which will certainly be less than enough for those who are eagerly waiting to play the blockbuster. However, it should make the wait a bit easier: the full game will be released by the end of the month, on February 27. But just go and play the demo already!
