Necronator

Necronator is a brutal strategy. You play as a necromancer and at first you army is only few skeletons. But later in the game you get better troops, for example orcs or zombies. More later you get some special heroes, Doggar a barbarian who was led by bloodlust into this dark army. Of course you can cast many spells of destruction killing and destroying everything. Your task is to kill everything on the map. At first it's just a fun abut later it comes into an open war. On the other side you can await tougher and tougher enemies and so heroes too. Big plus for improvements of your army.
