and i mean, i hate how titans can outrun even quetzes, so this guy being able to trot like a bronto but bash at the end isnt really that far fetched. Low speed but high impact

Ah but, in consideration these animals do have a sprint of sorts likely if put inside the game, however even if all three feet are on the ground so do elephants today, and the being large animals can get pretty fast for a few minutes. And being so large already a Isi would've been devestating in a charge.

I based the Isi on elephants, species ingame currently like the Gigas, Rexes, Allosaurus, and my dossiers of Carchar would be able predators for Isisaurus, and being unfriendly to humans is because how elephants are semi-friendly towards us. One wrong move naturally they'll get aggressive to keep us from being well hurtful. While a elephant in a Zoo that's been used to humans likely wouldn't be as aggressive.

Titanosaurs were some of the slowest creatures in real life. Also, it's aggression wouldnt be neccesary, being so large would already deter many predators. Some of the faster sauropods would be your smaller ones, like Camarasaurus. Large ones, like Titano or Isi, are proven that they HAD to ahve at leat three feet on the ground at once, or else they'd fall. An improvement, but needs more balancing. 6/10

Thank you my first two comments ever, and they are positive, thank you!

NIce balancing between utility and combat stuff, might have to be harder to tame than a bronto tho... overall great idea!

Thank you :D

Amazing, i hope the ark devs actully add this to the game!
