Biters

Biters will be our main problem in the game. They are the native inhabitants of the extraterrestrial world, and apart commonly they live peacefully with the worms. Biters are Artropodes's species that lives in group of constantly increasing number of nests and they spawn began small and grew up being medium and finally big biters (adult biters) and are very strong front us. Biters will attack our machines that produce pollution and later will kill us. If you look right you will see a common Biter's nest.
