This is a very cool campaign for the new Killzone 2 on PlayStation. Created by Agency Republic in London, the game is actually based around a tool bar (eg. google tool bar) that you download and install, then, as your browsing sites your killzone 2 tool bar game can randomly activate, saying “your under attack” from which you have 15 seconds to engage and start shooting rounds into your browser to take out enemies from the PlayStation game. But perhaps the best feature of all, is that you can instantly “ping” friends who have the tool bar game installed, bringing them directly into the battle on your computer! Check out the site here.
