Siege Hero (Viking Vengeance) is a new approach to the gameplay of Angry Birds series. Basically the most important difference is your perspective: You throw objects to the enemies by looking their eyes instead of using a sling to throw objects from left to right on the screen. So, it's a fresh experience and has lots of fun. Enjoy it!
Use your mouse to aim your targets and click left mouse button to throw stones. You must use the stones carefully for doing maximum harm to enemies because you have certain amount of stone.
