maybe an upgrade that allows you to pick up body parts and smack them and then another one like pick them up and throw they at them? longer bows size= more arrow like maybe the last bow size could shoot 3 arrows which use 3 bars maybe executions like your leg kicks their heel and then you jump and stab them in the chest and maybe a headbutt? and maybe a foot stomp so it like you put your foot on the ground and then all of the guys fall down and maybe King battle its a coop battle when some is the king that sits up there says my fellow robots i will kill the remaining humans and then they fight before they fight they each get 5 upgrade points and the king has a tone of health and maybe longer reach for the sword? and i thought of this maybe like you can grab the robot had and spin him and it hits the others thats it for now
