|First Discovered||Moon 16|
Occulus Enormus is the first truly aggressive genus you will encounter. Those three-eyed beasts will go directly to your nearest tower or refinery; consequently, barricades or high-powered weapons on the front line will be needed to stop them. They appear on the moon, beginning with level 16.
Unlike their smaller counterparts, they are very heavily armored. Heavy Blasters will not be very efficient; use a combination of Cooling Towers and nuclear Reactors if you don't have Blast Cannons or other heavy weapons to take care of them.
They will attack the nearest target, including Scarecrow. They will try to avoid scarecrow if it's not the nearest building, but will go straight for them otherwise. Since only the leader will do that, either one cannon turret or some Mines will be enough to destroy every Occulus Enormus coming at it.
See Armor for details on how armor works and how to deal with it.
