Supa... First, Glad you find it a challenge but Like all Games, there is a learning curve one must go through to understand how to play it better. Yes, it was intended that the Zombies can build Dogs without a Dog Resource. That was to prevent a Human Player from being able to shoot out Roads to prevent the Zombies from having Dogs as well as to make sure the Zombies could build Zombie Dogs in all buildings.
The New Version I have been working on is better in many ways. Difficult but with far better Power and ability. Much Larger and the Zombie Dogs are not such a problem and are more controlled.
Many Units are now controlled by requiring an Improvement or "Key Location" to Auto-produce them only. It has been almost impossible to have the AI build a unit when it is desired and the desired number of them, so I have forced this control to gain better game play.
The Zombies are far Stronger at direct fighting than the Human Units in general and they have many more Units but the Humans have extreme Bombard (Shoot) Power and that is the basic method of Play to Survive and Win.
The Zombies have 30 starting buildings now and when they capture the Hospital on Turn One, unless a Human is playing as the Authorities, they have 31. This Out Numbers the Human Player 5 to 1.
The Game requires fewer turns but game play time is much longer.
Many more New Units, Key Locations, Improvements and Buildings in the Game.
New Graphics additions throughout and all Text files have been worked on totally to address all Game factors for this New Game. Everything from Advisors to Labels and the Civilopedia has "miles" of additions and Links to be as complete as possible.
So Many additions and changes that I cannot begin to list them all.
What I hoped could be tested and adjusted in a month or two has become Five Months now... so I am continuing to Game Test and Adjust for now. I have been Game Testing just the Survivors although I do make adjustments for all Factions as I adjust the Survivors. That said, I will have to Game Test each Faction later but want to have the Basic Game Play established before I continue making the remaining Unit Additions. This is to sort of help "free my mind" from Game Play Factors so I can focus only on making the Desired Units. I have been working alone on Every Aspect of the Game since the Remake Release and it has been a Huge amount of work but all is developing as I want it to and Great Fun.
My Hope is that when I Finish this New Version, people will still be interested in it.
Just for a simple example this is the New Splash Screen I made to keep it above the other Game boxes on screen. As you can see on the mini map, the game is larger and has more buildings.
