These guys can be used for soaking up turrets and plants, but remember they destroy metal so why not let your regular Dino's tank most of the damage than use this beast to destroy all the metal structures. They aren't as tanky as they seem.
So to tame this you have to get all your dinos then attack it and after this it will try to hug you do not worry if your dinos die then it’s going good next wait till all your dink’s are dead then cry in a corner realising that this Dino should not be tamed by you and leave it to others while you just watch from the distance
Make lots of cannon balls Dododex is wrong. Must get full torp to "tame". If you can't trap it place cannon on the side of platform. Also sometimes shots will not register if titan is clipping on terrain.
