At the day 200, alpha overseer died by my hand. I beat the alpha overseer with 18 Theri, 2 Yuty, 1 Tek Rex, Theries had 22k hp 500-600 melee damage, 200 armor saddles, 20 cake each. Half of them died in the tek cave! : r/ARK
After lots of trial and error I finally soloed the Alpha Overseer and Tek Cave : r/ARK
