When I first saw one of these, I paused the game and looked it up. What I read was so horrific that I went straight back to base and crafted as many heavy turrets as I could and as much ammo as I could, to place around my base (which was in view of the swamp). Then I went on a metal run to get even more turrets. Put up about 12 before I felt safe.

Never actually fought one yet. Too scared 😭
