Pro tip: Don't use explosive weaponry and really bad rexes with no saddles like the devs did. Fab Snipers for taming it with little/no collateral damage, actually decent rexes + imprint + saddles to kill it
Try to hit the coropted glowing things around his body. Ice you have destroyed all, it should fall down on the ground knocked out. You do not need any taming food for it, Just go up to it and click tame to tame it. No need to build a saddle because it already comes with one.
Use tek gear and a fabricated sniper or use a mek. The mek does not work in split screen shoot the nodes carefully if you want a alpha titan be carefull for a root grab attack some times it glitches you under the map
Step one Simon it and kill it watch out for the hand beam stent 2 summoning it and shoot the nodes with a tek assault rifle they spawn dragons so ride dragon I recommended not to use a dinosaur if the green bar goes down a lot it won’t be an alpha and it will be weak
