Acid Glands in Grounded 2 might seem like science fiction, but in fact, they are as close to real life as it gets. You would imagine that these are related to some Bug(s) that spew acid, but you would be gravely mistaken. Instead, it belongs to a mundane Bug that can be seen in real life as frequently as you would spot an Orb Weaver hanging in the corner of your room.
In short, to get Acid Glands in Grounded 2, you will have to dispatch Red Soldier Ant. In real life, Red Ants secrete formic acid, also known as methanoic acid, when they bite their prey. This same principle has been applied to the game to make things realistic. You can also get Red Ant Parts and Red Ant Mandibles.
Where to find Red Soldier Ant to get Acid Glands in Grounded 2

While some resources occur naturally, like Mushroom Chunks that can be farmed using an Omni-Tool, Acid Glands have to be earned through combat. If you plan on stockpiling this resource, you'll need to fight a lot of Red Soldier Ants. Where better to find them than in their own homes?
The best place to find Red Soldier Ants is undoubtedly within the confines of Anthills. These can be found all over Brookhollow Park, but are not easy to walk into if you're not prepared.
Thus, instead of gunning for Ant Hills straight away, you may want to first fight some Larva. They are easier than Red Soldier Ants and will drop Acid Glands in Grounded 2 as well.
What to do with Acid Glands in Grounded 2?

Acid Glands can be used to create things like Rocky Rounds, Astonishing Acid, Snail Shell Plastron, and Red Ant Arm Guards, which have an item set bonus.
New recipes involving this ingredient will likely be added later, as the Grounded 2 Roadmap is stacked with hints of upcoming content. We could see the item put to use in more armor sets, weapons, and perhaps even decor.
