You should make it so the pharamoans fade compleetly after a while, cause ive found if your patiant enough and place your food properly, you can get all the ands trapped on the far side of the lake ^_^ or even just an auto return function in the ant AI where if it was out for x long without finding food returns to the nest
All 4 Endings
1) Close the portal in the evil graveyard (requires 15 survivers) 10 Days
2) Retake city hall and draft a constatution (requires 5 leaders, hospital, school, lab, church) 10 Days
3) Research cure for zombies (5 scientists, and need to own 3 labs) 10 Days
4) Reclaim the city (own the map and you win) However long it takes you ^_^
Also, you can have more then one lab researching the cure, this does not make it go any faster, just allows you to finish the cure ending mulitable times for more points (I have already finished a game that told me I had discovered 5 endings because of this.) Enjoy ^_^
I think having a little more diviristy between the baddies (and bosses) would be nice. Them either slowly marching across the screen with no guns, or staying over on the left and shooting at you gets kinda old. Even with that I still say its a great game. 5/5
