Scythers

Scythers are a classification of mechanoids that excel in melee combat, but can use their specialized charge lance for ranged attacks. They have no faction affiliation and are aggressive to all humans, and are often found near ancient ruins.

When Mike and Andrew raid an ancient ruin, the two see the Scythers opening up cryptosleep caskets and killing the people inside them. After Mike spots Noodles in a nearby casket, he sacrifices himself to give Andrew time to rescue Noodles from his casket before the Scythers kill him.
