Enemies
At the time, Factorio has two types of enemies; Biters and Worms. [0.7.0]
Biters
Biters are the main antagonists in the game. They are the native inhabitants of the extraterrestrial world and commonly live peacefully with worms. Biters are arthropods living in organic nests. They come in 3 sizes: small, medium and big. Biters are attracted by and enraged by pollution and will attempt to destroy its sources. They prefer to attack the player character, turrets and logistic bots and will stop searching for pollution if they can see and attack any of those. Biters deal physical damage.

Worms
The Worms are the natural allies of the Biters and will attack you if you get close enough. Worms will act like static turrets and will not follow you. Like Biters, worms come in 3 sizes, their power increasing with size. Worms deal acid damage. Despite how it looks, worm's projectile can neither deal damage to units other than the target nor can be dodged.
