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!
