Got to day 11 as the survivors before I gave up. 3 turns ago I had just under half the island. Once the Zombies took out the last Farmers and Authority building (Company died off loooong ago), they just came at me on all sides with tons of Omegas and Toxic Colossus's. They were amazingly smart and targeted all my hero units. In the past 3 turns I have lost all but 1 hero unit (Flamin' Hero), and 6 buildings! At least 2 more will go on the next turn... But there will be none as at this point there is no hope of recovery. Also been running at a 260 supply per turn deficit, and have been out of supplies for at least a day....
Next game I am debating to try again as the Survivors, as I know what worked and what didn't last time, or try it out as the Farmers...
As for improvements, I have a few, all minor:
1. Random spelling errors, I didn't take note of them, but nothing horrible.
2. When your Explosives Room explodes, your options and what they do are reversed - in other words when you click on Zoom in it dismisses it, and when you click on Dismiss it it zooms in (I forget your exact wording but you get my point).
3. Long turn times. I don't mind all the aiming and sniping, in fact I love it! It is the sloooowwwww Zombies that are killing me here. They take forever! When I quit the game above, the AI takes an hour to get through all those Zombie motions. I might not have given up if it took a few minutes per turn but an hour...
Anyways, all minor things, nothing major. When the Zombie turns start taking years I will just go do something else and come back, I will just miss whatever damage they've done to me :/
