Grounded 2: How to Unlock Ziplines and the Zip.R in Into the Abyss

Ziplines finally made it into Grounded 2 with the Into the Abyss update, and they let you rig up a personal fast-travel web across Brookhollow Park. The catch is that neither the blueprint nor the Zip.R tool you need to ride them just drops into your lap. You have to earn both by climbing to a hidden zone called the Crow’s Nest and then digging the Zip.R out of a very tall, very dangerous tree.

Quick answer: Climb to the Crow’s Nest at the top of the Pergola, grab the Pergola Optical Disk, slot it into a Research Station (Ranger Station), then buy the Zipline recipe for 2,500 Raw Science. To actually ride ziplines, collect the Zip.R tool from inside the hanging shoes in the Gnarly Bark area.

What you need before you start

Both the blueprint hunt and the tool hunt are heavy vertical climbs full of spiders and other bugs. Bring the right mounts and a way to survive falls before you commit.

Requirement	Why it matters
Orb Weaver Buggy	The only practical way up the Pergola and the upper Gnarly Bark branches; crosses spiderwebs without penalty
Black Soldier Ant Buggy	Needed to climb the bark interior on the Zip.R route
Dandelion tufts	Prevents instant death from fall damage when enemies knock you off the climb
2,500 Raw Science	Buys the Zipline recipe after you turn in the Pergola Optical Disk
Pergola Optical Disk	Unlocks the Zipline blueprint at a Research Station
Zip.R tool	The item that actually latches you onto a placed zipline

Reach the Crow’s Nest and grab the Pergola Optical Disk

The Zipline blueprint is locked behind a secret zone called the Crow’s Nest, which sits at the very top of the Pergola structure. This is a long climb, and a single bad fight can drop you all the way back down, so take it slow.

Travel to the Pergola region and head past the bicycle. Look for a juice box you can jump onto to begin ascending toward the secret zone.

From the top of the juice box, climb the vine branch that spirals upward. Enemies in the branches will try to throw you off, and without dandelion tufts a fall from here kills you instantly.

Use the Orb Weaver Buggy to handle the spiderwebs along the path. Find the cable and follow it to line up the route correctly, which leads to a tricky vertical jump along a gnarled branch and up onto a flower pot platform.

You will know it is the right flower pot because it has a couple of blue glowing mushrooms on it. Move to the middle of the pot, turn around, and follow the larger leaf up to a wooden beam with a cable. Jump onto the cable’s left side to reach a wooden structure.

Follow the wooden structure and dodge the Earwigs. Watch for the fireflies, then look to the right where the branches keep going up. That upward branch is your path.

Climb the gnarled branch and follow it left. Keep an eye on the Orb Weavers patrolling here and use their webs to keep climbing until the Crow’s Nest comes into view. Follow the branches where the Spiderlings are moving, then turn left again to find the final path up.

Note: If the spiders are wearing you down, a ranged setup like a Mage build works well here, since you can attack from a distance while your buggy soaks up the hits.

Once inside the nest, search the corpse for materials and the Zipline Test Plan, then pick up the Pergola Optical Disk sitting next to it.

Unlock the Zipline recipe at a Research Station

The Optical Disk on its own does not give you the blueprint. Take it back to any Research Station (also called a Ranger Station) and insert it there. That adds the Zipline to the Science Shop, where you then buy the recipe for 2,500 Raw Science.

Bring the Raw Science with you before you make the trip back. If you turn in the disk without enough, you will have to farm more and return before you can craft anything. You know it worked when the Zipline appears in your build menu after the purchase.

Note: This is the Into the Abyss route. Older Grounded advice about the Hedge Lab, BURG.L chips, or the Assistant Manager does not apply to unlocking ziplines here.

Find the Zip.R tool in Gnarly Bark

You can build ziplines with the recipe alone, but you cannot ride them without the Zip.R. That tool is hidden inside a pair of hanging shoes near the top of the Gnarly Bark area. Bring both the Black Soldier Ant Buggy and the Orb Weaver Buggy for this one, since you swap between them.

Head to Gnarly Bark and find the branch covered in brown moss. Climb it with the Orb Weaver Buggy until you spot an entrance into the rotten tree.

Inside, switch to the Black Soldier Ant and climb the bark, pushing past the Cockroach nest and the Earwigs. You will pop out through a hole in the bark next to a bridge built from matches and a wax candle. Climb it and jump to keep going up.

Go back inside and you will reach a Sour Puddle, which causes Tang Corrosion, so keep your distance. Grab the Gnarly Bark Aquatic Optical Disk from the nearby corpse and keep climbing.

When you emerge near the top, switch back to the Orb Weaver Buggy and climb the branches until you see a pair of shoes hanging from one of them. That is your destination.

Work your way across the webs and branches, defeat the large spider lurking around the shoes, then access the shoes and take the Zip.R from the corpse hidden inside.

Zipline Anchor crafting recipes

A working zipline needs two endpoints. You can use two standard Zipline Anchors, or pair a Zipline Anchor with a Zipline Wall Anchor when one end mounts to a surface. Exact material counts can shift between versions, so check your build menu if the numbers differ.

Structure	Materials
Zipline Anchor	1x Silk Rope (Web), 4x Clay, 5x Weed Stem
Zipline Wall Anchor	1x Silk Rope (Web), Clay, Bee Stinger (Bee Parts)

Build, connect, and ride your ziplines

Once you have the anchors crafted, setting up a line is quick as long as your two endpoints are roughly aligned. If they are badly off from each other, the game will refuse to connect them.

How to Build a Zipline in Grounded 2 Into the AByss (1)

Place one Zipline Anchor at the start of your route, then place a second Zipline Anchor or a Zipline Wall Anchor at the destination. Keep them relatively level with each other. The Handy Gnat building mode helps you plan an entire chain of ziplines at once.

Leave building mode so you can interact with the structure. On PC, press E on the anchor to start connecting it.

In the menu that pops up, look at the anchor you want to link and confirm the connection with right-click on PC. The rope stretches between the two anchors once it is linked.

To ride, jump and latch onto the line with the Zip.R by pressing E. You will slide along at high speed. Chain several anchors together to build a full circuit around your base and beyond.

Ziplines are a separate system from the Pneumatic Transit System, so treat them as your own custom point-to-point network for tall landmarks, towers, and bases rather than a replacement for PTS stations. High central spots like the Pergola concrete blocks and the branches around Gnarly Bark make natural zipline hubs once the whole setup is in place.
