Nobody knows where these trolls and orcs came from, but one thing is known for sure, they won't stop until they kill everyone they see. Can you defend your home?
It doesn't matter where these creatures came from, they are here and they seek for blood and destruction. The assault is unavoidable and you have to think about the defence strategy. Kill waves of ugly creatures and take a break before another one will come. Upgrade your abilities and weapons while you wait for another attack and destroy them again.
