Miner mechs are machines developed by Goblins for use underground. They can kill zombies as well, but some may hurt the player.
Green Mechs are player-friendly and will attack zombies, but they are passive to zealots and insects. They have glowing green lights on them that allows you to see them in the dark. They are mostly grey in color, with two giant arms with big drills on them. They have rather thin legs in comparison to the rest of their body.
Red Mechs have the same general appearance but have a red body. They are hostile and will attack the player as well as zombies insects goblins and zealots. When killed they will drop XP. It is suggested to kill them with a range weapon, as they can inflict lots of damage.
