It is the year 1000, and an unexpected surprise is headed for Europe...
At its simplest, the idea is risk... with zombies. Zombies will slowly encroach on human territories and the humans will fight back, eventually they will eradicate all the zombies or be consumed by the ever growing horde.
Rather than being a "Wall 'em Up" like Eras Zombie Invasion, I intend this to be map to be a lot more Tactical, at first zombies will be able to tackle humans on even footing during the medieval ages, but as technology improves, the zombies will need to be more subtle and infect the humans population base as opposed to charging headlong at the humans troops. Alot of the skill in playing as zombies will be scouting effectively and choosing the easiest and therefore best target to attack (if you face tough opposition you're unlikely to end up with more zombies than you started with, or even any at all!).
The humans also have a more difficult time than walling and waiting. They must increase technology if they want to effectively eradicate zombies and keep up with zombie evolution, but to do that they need lots of people to gather resources who will be much more vulnerable than soldiers.
How (I think :D) it improves on other zombie invasion maps
Thanks for Reading.
