“Produces heavy tanks on defense.”
General Information Edit
Bunkers are defensive buildings that will spawn Heavy Tanks when enemy troops go into its range.
The Bunker is a unique defensive building since it requires resources in order to function. So when the Heavy Tanks spawned by the Bunker get destroyed or betrayed, it requires Oil to replace them. Bunkers can hold up to 5 Heavy Tanks.
Bunkers spawn faster if they are within the radius of the Acropolis.
Bunkers are available in the Industrial Age.
Like troop-training defensive buildings, Bunkers can detect Commandos.
The first wave of Heavy Tanks produced by the Bunker take 10 seconds. The waves after that take one minute.
Attacking Strategies Edit
Bunkers have low hitpoints so using Demolition and Barrage to take them out are very effective.
Best way of dealing with spawned Heavy Tanks is using Fighters on them. Betrayal works great too
Decoys doesn't work well on Bunkers as any spawn Heavy Tank can destroy it and quickly add up to your burden of dealing with defenders.
On scouting a base, if the Bunker is dark inside and have no smoke coming out of the chimney then it means it has run out of oil and as such would not produce any Heavy Tank when under attack.
Bunkers in war bases doesn't run out of oil. If its dark inside then its probably under upgrade in the main base
Defensive Strategies Edit
Many attackers preferred to use Fighters on spawned Heavy Tanks so is advisable to have Bunkers near an Air Defense.
Is best to avoid burying Bunkers in deep wall mazes since Heavy Tanks move very slow.
Placing them near wonders such as Acropolis and Angkor Wat makes the Bunker spawn faster and heal the spawned Heavy Tanks respectively.
Always refill the oil require for the Bunker to stay active after each attack on your base.
