The Omega... Glad you are enjoying the game.
Testers I will try to explain the issues some of you have brought up.
Wade through this if possible 
It is important that you play an entire game because you will think all is well and that you have a Great Position in the early game. Playing as the Survivors, you will be able to gain very good positions as a Human because you can actually think and apply your strategies against the AI. The power the Zombies have is that they usually gain all other buildings in the game concerning the Other Factions with just a couple exceptions. The More Buildings the Zombies have the more extreme power they will have ...especially later. IF you manage to gain a Strong position early, do not relax, continue as strong as you have played because when the Zombies obtain many buildings and their later Techs, you may be surprised at their strength then.
...IF you fail to gain at least 3 more buildings by the time the Zombies get well past Zombiegeddon, you will have a very tough time trying to win.
The Survivors can certainly stay on the Island and Kill the Zombies eventually if a player wants to win this way but it is much faster and easier to go for the Airport and get off the Island. The Company can Win Faster by building the Spaceship than staying and killing all Zombies on the Island but this is the players decision. The game is set up to allow any faction to be able to win by taking over all buildings on the Island but the Survivors and Company have easier and faster winning options.
IF the game was set up where the Survivors or Company never had any chance at all to kill all the Zombies and the only way for them to win was to get to the Airport or build a Spaceship to get off the Island...the Survivors and Company would probably lose most games if not all because they would not be able to have the stronger units they have now that are capable of Killing the Zombies with Good Long Game play skills.
...it was very tough to be able to have any Bombarding units in the game and continue to have a challenging game. The Bombard Units are Fun and helpful to say the least but because the stronger units were added along with other game additions that provide more strenght for the Human Factions, the Zombies were strengthened to be able to contend with the Stronger game situations.
Zombie Goo is available to all Zombie Buildings because that allows each building to be able to have the needed resource to build the stronger units without problems gaining or losing the needed resource. In Other words...the Zombies will have the resources they need to build any unit available to them in all buildings except the Airport...it does not have Zombiegoo. The Other reason is that when a player discovers where the Zombiegoo is, they could prevent access and take away the Zombies ability to build the stronger units they need. That would be ok but because the game now has very strong units for all factions, there is no need in that type of strategy. That is learned from playing Normal CIV Games and we wanted to prevent this. Some Buildings have Zombiegoo inside the building such as the Zombie Bastion so even if you try to take away their Zombiegood, you cannot.
...all factions have access to all resources they need in the game IF they hang on to their Starting Buildings or if some are lost, they can gain others that have a resource they need. Resources do not dissappear or move around. This game takes place over days and is not like a CIV Game that takes place over Centuries..Resources would not be used up in this game.
Virote_Considon... I understand you were using "gamespeak"...I was trying to provide the over all game situation concerning Buildings and what the Survivors can do. Even in a Zombie Movie, survivors tend to do ok until later when the Zombies gain more power. IF this game was set too difficult for most players on 12A level, people would not enjoy playing it. There are many limitations to what can be set up for game play with the Hard Coded Game Engine. Unless I am mistaken, the Zombies always win in the Movies and the only way to set that up in this game would be to make it impossible to ever win. The Aim was to try and have the game as close as possible to the Feel of a Zombie Movie and add the ability to win as well.
IF this game was only playable as the Company and Survivors, it could be set up where the only way those two factions could win would be if they escaped in their own ways. Because the Authorities and Farmers must win by Conquest and they are playable as a Human, the Survivors and Company need to have the way to deal with them because they will also go to war against the Survivors and Company. The Farmers and Authorities must have strong units to be able to Kill the Zombies and win by Conquest so this is all another area that affects what can be set up for game play.
Believe me, it would have been far easier to only set up the Survivors and Company as playable Factions...then set the game where they would never be able to Beat the Zombies but rather Win the game by escape. As it is now players have several choices and this is much like 5 separate games that all play together. Just not as simple as it may seem.
There are far too many factors that had to be taken into consideration concerning the units and game settings than could be explained here. Branching variables that affect many others that do not immediately present themselves when adjusting units or game play additions. All factions had to be game tested with each adjustment, change and addition. Please keep in mind the level you are playing and judge accordingly.
The Company is the easiest to play other than the Farmers because all the Company needs to do is Block access to their buildings at the narrow areas that lead to them. The AI will then go after another Faction.
The Survivors are farther away from the Airport and have a long battle to get there so they need to gain buildings as fast as they can.
The Authorities are surrounded and their buildings are spread out. This is why they were the first to gain the SWAT with Bombard "Snipe" power. They also gain the Most power later if played well. The point there is that if anyone could destroy the Zombies on Paradise Island, the Authorities would be the ones capable of doing it. The Powerful weapons that the Authorities gain later will come in handy on higher levels. IF you discover that the Stronger weapons were not needed to win on level 12A...try level 18 and you may be gld you have them if you can hang on to the Military base and Armory.
My suggestion is if the game is too easy to play on 12A level, play a higher level such as 18 and see if that fits what you are looking for better. IF you play a game on Banned as the Survivors, I honestly believe the only way players could win would be to escape.
Please play several entire games on 12A...then see what you think about the settings for that Level. I always play deity level for all CIV games so Monarch or in this case 12A is not a problem and I would never lose any this game if I play 12A.
I hope everyone understands that the reason to test 12A is to make sure the settings and game play are set correctly for that level. It is not a matter of if it is too easy or too difficult for any one player because that is a matter of experience. IF level 12A is set appropriately for level 12A by the general Opinions of all testers, all other levels will also be set appropriately.
Whew!...That's a Long Post... 
) What I was stating was that the survivors seem too easy as compared to, say, the company, and every time I play with them, I seem to be able to take way too many buildings without loosing anything. The problem is, they don't have much in the form of threat around them. As soon as they have the Graveyard and the hospital, they can stop worrying about any assault from their rear (unlike the Authorities, who are surrounded by zombie buildings, and the Company, because they start the closest to the Research Center). As the survivors, I rarely need to worry about the church, which is pretty much "that flank".
