A quick look at the Killzone.com leaderboards shows that Killzone 2 has just reached the 1 million players online milestone, just 2 months after its release. By that count, approximately 2/3 of the people that have purchased the game have played a match online.
Guerilla will be further enhancing Killzone 2's multiplayer experience with the Steel and Titanium DLC package, which includes 2 new multiplayer maps and new trophies to collect, later this week. Killzone.com was also recently updated, allowing you to download match replays.
Killzone 2 is a first person shooter developed by Guerilla Games. The game is available now, exclusively for the PS3.
