Since nobody gave a good tutorial on how to tame this beautiful beastie, here ya go:

What you need to bring:

Mastercraft Shotgun or Sniper Rifle

Lotta rounds for the gun

At least 30 Bio Toxin

50 Exceptional Kibble(just in case)

Acro Saddle(for after it’s tamed)

A flyer or really fast mount that you can wield the gun from

Anyway here’s how to tame this beautiful creature:

Firstly, find an Acro, then once you find one that you deem worthy of joining your army start shooting it on your mount’s back from a close-ish range, after it enters shield stance unload on it until you get the right roar, two roars exist. The fake roar is way less dramatic than the actual one, which you can tell apart because the real one, the Acro will raise itself up and roar at you, and there’s also an effect around it. When it does the real roar, dismount your creature and run up to its mouth (terrifying, I know), and mash E or whatever a console players interact key is. If you miss the feed, it’ll enter adrenaline mode and you gotta RUN FOR YOUR LIFE, after about 35 seconds, the adrenaline is over, so get back to shooting the Acro’s poor face.

Rinse and repeat this process (preferably getting the Bio Toxin in its mouth), and once this glorious beast finally goes down, yeet that kibble into its inventory and give it a bit (put whatever Bio Toxin you have left in there too just in case), after a few minutes or so, the Acro wakes up and is ready to be your war mount!

I figured out the easiest way to tame them! You'll need a Deinosuchus since they barely get knocked back from the Acro due to their low stance.

Ride the Deino and bite the Acro until the Acro does it's feeding roar, then dismount quickly and feed the biotoxin. Get back on the Deino and repeat. You'll be tanking the Acro's attacks so watch your Deino's health. When the Acro does its stomp or fake roar, stay on the Deino and you'll only get knocked back a tiny amount. You can easily knock a max one out in a couple of minutes this way.

You can’t tranq this Dino you must shoot it until it roars then run up to its lower jaw and feed it biotoxin. My buddy try to tranq it and used 88 of our tranqs. Enjoy this info like we would’ve

When taming these dont try to trap them as it typically causes them to never go into shield stance. Fret not i have an easy guide, once you get it into shield stance count how many shots it takes to enrage it (normally 5 with a good pump) shoot your amount of counted shots then back up and it will roar, then run up and feed it your narcotic or more ideally biotoxin then immediately back up a good distance and as soon as it is done with its animation it SHOULD go right back into shield stance allowing you to rinse and repeat this method safely on foot. WORDS OF WARNING kill everything nearby as to not mess with the process, you know you are safe to start shooting when it stands straight then goes into its shield stance, ONLY approach it AFTER it does the correct roar since it has 2 roars, the one you are looking for and a fake/taunting roar which if approached when its doing this second roar will cause it to enrage and and start attacking everything for 30 seconds and will kill you very quickly. IF it does the fake roar simply stand back a good bit and wait for it to finish, after it does it'll do the correct roar and you then run up and feed it like normal. with this method and a little practice you can tame one without ever really getting hit whilst on foot. ALSO the second roar isnt nearly as loud as the first and looks a bit different and the acro will laugh at you (literally) after doing this fake roar if it doesnt get enraged by tricking you. Lastly these things are BEASTS, you and a tribemate can grab 2 bred acros with asc saddles and kill alpha monkey with just those 2 acros, they can also solo the hard ice cave on the island but youll want a good saddle, hope this helps and like so others may see

These things are a total pain to tame, and i highly suggest you find tutorials before taming, because i guarantee death for anyone who doesnt know what their doing.

They do not roar if their on bad landscape, make sure to lure them to a flat area.

Traps are optional, but highly recommended.

Low quality weaponry is not advised. Always have a high quality shotgun (preferably) or a fabricated sniper.

Damage from creatures will not work.

You can use a extremely tanky creature to tank hits so you can avoid harm (creatures like a deinosuchus) while you shoot it.

It has 2 roars. A healing roar, and the roar when your ment to feed it. The healing roar starts with it “inspecting” you and its head is lowered. It will then aggressively throw its head up to roar. Do not approach at this time. The second has it immediately roar. Feed and run.

I hope this helps someone tame a acro, good luck searching and happy taming.

You don't need to target its mouth when feeding narcotics or biotoxin, any part of its body will give you the option to feed.

A bit confusing, but a good way to tell a wild acros damage stat without mods:

Use your own acro. Get into shield stance, and force wild acro into shield stance. Whatever the damage done by the acros BITE in shield stance to your own acro in shield stance is the damage stat. For example, if it does 33 damage per bite, it has 33 points into melee. Nothing game breaking but I thought I’d share

If you use an ascended shotgun, watch how many times you unload in them. Also use bio toxic, narco will take way too long to tame them with.

Pro tip, don't use a stereotypical metal box to trap an Acro. If you really need to restrict it's movement, you can use a wall of metal billboards, so long as it can still move around. The easiest way I learned is to just back up as it walks to you, and if it does the fake out roar then run away from it

An easy way to tame him once you are into late-game and have a Tek chestplate.

-a good amount of Bio toxin.

-try avoiding Pump shotguns and rather go for a fabricated sniper rifle. (The rifle does damage in per bullet which makes it easier to control the situation)

-a tek chestplate.

So basically you just hover over him and tick away his health until he goes into a defensive stance. Tick away some more and he SOMETIMES does his adrenaline roar. Not to be mistaken with his health restoration roar. Once he does his roar you need to dive bomb him by disabling your chestplate and spamming the feeding button. And basically rinse and repeat!

And if somehow you screw up and do his health too low you can lead him to weak creatures, he will eat them and restore about 50% of his health which grants you a second chance!

Tested taming extensively.

1. The acro does not seem to care about the damage output you are dealing while you shoot it, it cares how many times you shoot it and with what weapon. Use primitive to reduce the chances of killing it. Shotgun is best.

2. While it is doing the fake roar it will constantly regenerate health to full for the entire duration of the animation, this is a great opportunity to lay into it and force it back into shield mode.

3. If you do not shoot it during the false roar, it will become impervious to damage for about 5-6 seconds, do not waste your ammo during this time.

Be careful because if one is to low of a level you might accidentally kill it when trying to tame it

Having tamed quite a few of these on center and on the new gen one map I've learned a few things. First come prepared, make sure you have enough biotoxin or narcotics and ammo. Second you don't have to use a pump shotgun, double barrel feels much better because it's higher damage and doesn't waste as many shots. And last taming on foot is a lot easier than you think, just kite it shoot it and feed. Good luck

Literally all you need is a good deinosuchus, 100+ biotoxin, and mutton. Just use the regular attack (NOT THE GIGA BITE EVER) and when it roars dismount and feed it the biotoxin and just repeat, easiest way to tame it in my opinion.

Just don't let up. After each feeding of narcotic or biotoxin. You can continue pumping damage into it. If the does the fake raor. Continue to shoot it while it does this. By the end of the fake roar it should do a real one. If you miss a feeding it will go into adrenaline stat. At which point it will NOT go to shield stance and you must wait for it to stop glowing red. I don't usually clear out wildlife as i use them to heal the Acro if I do mess up. Good luck and hope you get the best Acro's!

Awesome tame ,a little slow but it makes up for it with coolness!

Biotoxin in your last slot. Goot shooter with good damage and ammo.

Find acro you want to tame. Clear the area of other wilds when its not aggroed shoot it untill it goes into stance/guard this means it walking towards you sideways slowly, a few more shots will make it roar. There are THREE roars only one you can feed on and its the roar where the acro throw it head up and back down qucikly and roars mouth wide open. Run and spawn interact, on playstaion its triangle PC 'E" if successful the acro will shake its head like it had a bad taste in its mouth. I run towards its tail ehich makes the acri turn to find ou giving you time to get some distance. Acro will still be in guard stance shoot it again untill you get a feed roar. Repeat untill it knocks out. BEWARE if you miss a feed it will rage and wont heal and trying ti shoot it back into guard will onky kill it. You need to lure it to a dead dino to eat and onky then can you continue the taming process. The low rumble roar with head low the acro will exit guard stance but you can shoot it back into guard stance after this roar.

Always spam interact when feeding narco/biotoxin as sometimes you can pick up stone or berries instead and miss a feed. Do not miss a feed. If you do give it time to kill somethine or you will kill it.

For me the most important thing taming these guys has been to have a large, open space. They seem to not enter the taming roar if they have to navigate around anything. Pick an open spot, but also clear trees and other blockers.

1000+ dura flak and capped shotty just run circles around it even with a wild 150, doesn’t inflict crazy damage.. Easy as

Shocking tranq darts don,t work
