Use a quetzal and place cannons and fly around the titanosaurs use 2 players on quetzal and 1 player or 2 on ground running around to keep it in 1 spot so that the titanosaurosu will be around the same spot. won't need to descend or ascend and easily knock it out. As the players on ground could use rockets to take down this massive Dino down. The main use for this Dino is to raid it can destroy metal bases easily and has high health.
You hit it with cannons on a quetzal. Go for it’s head. It’s torpor won’t drain either so take your time. They can’t eat just stuff a platform saddle on the titan once KO’ed. You use daedons to heal it when it’s food level is low.
If you try taming these guys, tame a Quetzal first and equip it with a platform saddle. Then, put 2 storage boxes on it and a cannon. Make sure you make LOTS of cannon balls. Then, shoot the titan in the head.
