This game is so much fun. And more, it has replay value. Try to kill off everyone, or no one. Scare the adults away first. My first time I killed off two people. And I laughed...
I think I've figured out the rank stars. For Destroy and Secure, you need to finish the level as quickly as possible. For Defense, you need to FINISH with as close to full health as possible (this means it doesn't matter how much you lose if there are health packs on the field, so save them for the last few seconds). For Cut Power, Intel, and Rescue, you need to destroy everything (including buildings that all civilians have evacuated out of) before you finish the level. I hope this helps other players who are confused.
Let me start by saying that I agree with everyone; this is a fun, cute game. I do have one small problem with it, though. Is anybody else having trouble with some of the in-game achievements? It didn't seem to recognize anything I did outside of the game, such as visiting the FunFlow page or becoming a fan, and I was only awarded the achievement for evolving to Tweenchin after I had evolved to Mature, Mature after evolving into Champion, and I still don't have the Champion achievement.
One question. How do you get a higher 'rank' on the special levels? It's easy to figure out how to get gold stars with 'time' and 'kills', but I'm trying everything I can think of for rank and coming up with bronze, at best.
A great game. You've taken everything good about EBF2 and improved it. Only one complaint: why do you keep the damn skeleton minigame? It's annoying as hell! But, that's my opinion...
My first game, I died so many times that I lost just after searching all but one of the city blocks. My second game, I take the subway, walk in the first door I see, and there she is. A fun game, and I will play it again, but seriously... WTF?
