How to get the Sparta badge: get a maxed-out grenade launcher, 2 basic missile launchers, about 40 gunmen and whatever else you want. Shoot grenades non-stop and eventually you'll get the badge.
Five stars from me, but moving during a battle is completely counter-intuitive. I kept pressing the arrow keys and then getting irritated when they did nothing. Can you modify this in the next game?
Very addictive, and artwork is awesome. I feel like there are too many life-giving cards, and not enough monsters, but that's not enough for me to drop my rating. 5/5.
It would appear that if you want the hard badge, you just have to keep restarting the game over and over until the first thing you read is "disease spotted in Madagascar".
