U.K.-based Agency Republic has launched a unique web game that promotes Sony Playstation 3's new Killzone 2 release.
You can visit the Killzone web game site to download and install a toolbar that engages a spontaneous shoot-em-up battle with the game's evil Helghast characters while you surf the web. For example, when you visit sites like Google, Flickr, Yahoo or MSN, the toolbar randomly activates to say "you are under attack." You then have 15 seconds to engage the toolbar, start the game and open fire on the evildoers. Participants can also activate "squad play" where they can ping other friends who've installed the toolbar to take part in the same battle.
