Few will argue that Killzone 2 won’t be one of the biggest game launches this year. The game will be a PS3 exclusive title and will launch on February 27th. Part of the launch for the game is a webgame called Killzone 2 the webgame.

The Helghast can strike at anytime while you are online like when you are surfing the Internet or checking email. To play the game you register at Killzonewebgame.com and install a plug-in for your web browser. The plug-in is available for Firefox x3 and IE 6 and 7. The game uses 3D models of the Helghast from the actual game.

As you surf the net the Helghast can be waiting for you on certain websites and you have to battle them. You can opt out of the fight if you don’t want to play. You center your crosshair on the enemy and if you miss, chunks are blown out of the web page behind them. You can fight alone or as part of a squad, you chose. To add someone to your squad just give them your squad ID and teammates are contacted when a battle starts.
