On an unofficial server my tribe was raided the opponent and us both low leveled but the opponent won anyways and I was the only person not at the base because I promised the tribe leader aka my best friend IRL that I would tame two high end allosauruses one male one female. Since I was extremely experienced I managed to complete my promise. Before I went back I decided I would breed them too. I leveled up and soon got fabricated pistol pump shotgun and assault rifle because I grind gigas and brontos with the help of my allos. So I went back to my tribe base for revenge and it was under control by the other tribe. They thought they already won and celebrated every time they were online for four REAL days and I spent those time grinding xp. I also bred my allos many more times so they were an army when I got back. I snuck my mesopithecus into the base and opened the behemoth gate. It was pretty much like the final battle in avengers endgame but I turned out victorious in the end.
