Um... can you create a super unit after you finished the game and upgraded all the upgrades so you stay interested for a little while after beating the game? Theres not really any point in the devil cuz once you get it, you've finished the game and it's boring.
when you say the last boss, do you mean gordzak or the hidden content thing that I still don't know what is? I think gordzak was very easy, but I still need 1 more thing in my bestiary, the one that looks like a spider with bunny ears!! GRR!!!
