Nacht der Hölle 2

NOTE- To kill a ghost, you need the ghost-buster gun.((ELECTRICITY ADDED! It costs $1000 to activate the lightning which will kill all enemies that try to enter the biulding for 1 minute)) The first wave finally ended. So you and the rest started looking for a fort and found the perfect spot. An abandoned German biulding. Sand bag defences have been set up to slow the enemies down. But that will not be enough this time.. For, there are over 20 new types of enemies...
