As well as conquering and pillaging, you also have to recover various items strewn around the levels in order to upgrade your private tower into the ultimate evil “crib.” That includes opening up a forge where you can create upgraded armor and weapons by sacrificing your minions, getting yourself a buxom wench and decorating the place to your evil tastes.
However, it’s the minions themselves that are the highlight of the game. You start with only brown minions (strong attack) but will soon rescue three more hives, bringing the red (fire-resistant, can throw fireballs and put fires out), blue (water-resistant and can heal other minions but weak to attacks) and green (resistant to poison and possessing a good stealth attack) minions under your control too. With only a limited number of minions at your disposal at any one time, you’ll use these little critters to rescue tower parts, take down enemies (after which you can harvest their life force, therefore earning you more minions) and generally pillage everything in sight. After all, evil overlords don’t spend their days making daisy chains and cuddling kittens.
