I think Sarcos are amazing mounts. When in water, they are decently fast and don't have an oxygen stat. Also they don't run out of stamina because it doesn't go down at all. They are also pretty good land mounts. Although they are very slow, they are pretty powerful. I wouldn't suggest fighting anything harder than a pleseosaur and on land nothing harder than a Rex. All in all, I think Sarcos are amazing mounts!
During my first 30 days of playing on my single player world, I was able to take 4 of these absolute beasts. We were UNSTOPPABLE. That was until an Alpha Megladon absolutely wrecked all four of them. Can I get an F for my boys
The Sarco has been one of my most useful tames- especially for early/mid-game. I have tamed countless Rexs, Allos and Carnos simply from firing tranqs atop one of these in a river. Of course, you need to find these carnivores by water for it to be effective, but when you do, you have yourself an easy tame provided you have enough tranqs.
Good mount to take into rivers and even the ocean. Good for hunting fish and I've even seen it beat a megladon. But never use it to fight a Rex because if things go south it is a very slow land mount. Short and sweet it is a hunting mount
