This is a RPG sandbox game! You will get it for €9.95(because it's developed by only one swedish man) Its a mixture of wow and l4d (at nights zombies are crawling around the place!) This is also the fastest growing web phenomen!

Reminds me of some of the old Nintendo games.
Where are the zombies?

[Gnome-father]

Change the difficulty to Easy, Normal or Hard and wait for the night! Creepers( exploding zombies), Giant spiders and Dead Archers are some of the creatures that only appear durning the night! When the sun sets all the zombies will burn to death, except Creepers and Spiders.
You can also find Cows, Pigs, Sheeps and "Hens"

BTW you need to buy the alpha, not the classic
