I defeated the overseer with the zero dinosaurs. This is very true. I use the tech suit to fly around and avoid the enemy. I shot down all the drones that shot me from above, and I literally obliterated the overseer with no dinosaurs not a one. This is a very true story I did not want to risk losing a single Dino. I defeated all. The gamma bosses so I can get to the overseer and that new dinosaur which is the carchar I saw it when I was just about to get closer and closer to the overseer when I was at the gate to the freezing area of the tech cave, I saw one is shares the spawn The giga so I saw it at the main entrance hall so I loaded into the lava once I did that I went through the main entrance hall, and then I approached the overseer and this is the people who have never fought it before as well. They can change to what boss it is, it can change to the brood, mother, the gorilla, and the dragon. The overseer dragon makes you really cold with its fire as well as I use the tech suit. I was not getting killed by the fire my guns broke, so I use my tech sword and obliterated the boss punch that up sign if this helped
