poison water is the easiest to use and win with if you choose to be neutral because of poison death ability. Use poison wave and poison death to annihilate almost anyone.
@ddo1167 when you click continue after you finish a campaign, it will say that you haven't conquered the last city but if you go to the upgrade screen it will say that you have the gold.
Mission 10 is way too hard. You shoot the alien commander and he teleports away, comes back with like five shields and shoots you in the face then goes away. And several times he was't shielded, I fired a shotgun in his face and he takes no damage.
Very fun at first but then i start getting bored when i have to do the same level over and over to get the infamy to upgrade. Also, you have a huge army of evil beings who won't step on the grass or try to destroy a tower. And some tiny village in the middle of nowhere has towers that can survive an earthquake. It doesn't make sense. But still, 4/5
It gets boring after a while because once you have an amazing army all you do is attack a city, kill everyone then go to another city and do the same thing. Add a bit more variety, like defending a city using the city garrison and your character.
