-----------Herose, the unfinished machine-------------------- you should know the controls by now. if not. you should aadoaa the base series first. New Mechanic for this boss, you are able to dash through its segments. this worm will use lasers, bombs, rockets and minions to try and kill you. positioning is really important for this boss fight so make sure you aren't in the way of any danger. literally every weapon can be good for this boss depending on the circumstance, some even have some special interactions between the boss.
