A running game which is certainly different than anything you might have played in your life. Run through dark sewers, avoid nuclear waste and the zombies that will literally devour you if you get too close to them!
Find Vlad, the last hope for the world, that is your mission. But first you must make it through the sewers! The government mustn't know about your attempts, which means that the only way to get through to Vlad is underground. But it's not any safer!
If dark is not dark enough, how about trying the Hardcore Mode? It's even darker, has more obstacles and more zombies!
