Zombies are our main opponents in the game. Their strength and amounts depend on the level of infection rather than the difficulty of the game. You can choose from 5 infection levels. Consider starting with the lowest one - you'll see how many zombies inhabit the area and learn to fight them off.
Types of zombies
There are three different types of zombies:
Common - encountered in large groups. Normal zombies are rather weak and their damage is low. Usually, 4 attacks of the archer get the job done. Sometimes found standing alone on empty plains.
Tanks - biggest zombies in game. Their damage is low, but you'll spend a lot of ammo to destroy them. Tanks often appear with a group of normal zombies and cover them from your fire.
Runners - quick on their feet, will attack your soldiers without warning. They also inform you of the size of the next herd and how fast will it appear at your gates.
Venom - spits a corrosive (toxic acid), infecting heroes & colonists. He's got a high damage and attacks several units in one time.
Harpy - fast and dangerous. They can jump over walls. It is best to pit snipers against them, who will deal with them very quickly.
- Swarms are large hordes of zombies appearing throughout the course of the match. Their target is the Command Center. If the zombies manage to reach the center, the game is over. Swarms consist of various types of zombies, while their size and roster are influenced by the currently chosen difficulty level.
- Swarms can be divided into two groups:
- Scripted - the appearance of the swarm will be signalled by a message that contains the information concerning the time and the location of the attack. The music in game will change and a yellow skull will appear on the minimap.
- Random - appear randomly after the second scripted attack. These groups are much smaller than the scripted swarms - keep track of your troops in order to not be caught off guard.
You can also encounter Zombie settlements found across the map. Such settlements consist of many buildings, each containing a large group of zombies. If you encounter one of such settlements during early phase of the game, try to wall it away from your troops and buildings.
An attempt to engage the settlement before setting up a proper colony will probably end with your death. To defeat a Zombie settlement, build at least 50 archers and 20 soldiers. Soldiers should attack the buildings, while rangers should engage the incoming zombies who will leave the buildings en masse. Destroying a zombie settlement gives you resources and/or money.
