The current Tundra farm uses the fence ledge behind the tree, best held with Bastion drones because pulling out a gun can knock you off.
The best current Tundra route in Survive Zombie Arena is the fence ledge behind the tree beside the shed. The fast patch removed the earlier safe spots, so this is the farm to use now: get onto the narrow ledge, tuck behind the tree, keep your gun away, and let Bastion drones, turrets, or Celestial damage clear the waves.
Current Tundra glitch status after the patch
| Spot | Status |
|---|---|
| Shed-side fence ledge behind the tree | Working as the main Tundra farming spot |
| House chimney, bookshelves, and windows | Patched |
| Cliff-edge hang spot | Patched during live testing |
| Shed-back shelter ledge | Patched in current servers |
| Wall shelter clip | Patched in current servers |
KEY!
Use the shed-side fence ledge behind the tree, where zombies path into an invisible wall while your class damage does the work. Skip the older house, cliff, and shelter-clip spots in current servers. Old servers can still have leftover behavior, but those routes disappear once the server updates.
How to use Tundra fence ledge glitch in Survive Zombie Arena
This route puts you on the fence ledge beside the shed, then uses drones, turrets, or Celestial damage while zombies fail to reach you.
STEP 1/9
Go to the shed-side fence

Move to the fence area in front of the small shed on Tundra.
STEP 2/9
Start walking down the fence ledge

Step onto the narrow ledge beside the fence and keep moving along it.
STEP 3/9
Hug the ledge tightly

Stay pressed toward the edge so your character holds the spot and does not slip out.
STEP 4/9
Move behind the tree

Continue until you are tucked behind the tree and fence area.
STEP 5/9
Keep your gun away

Do not pull out your gun here, because the weapon stance can push your character off the ledge.
STEP 6/9
Let Bastion drones kill for you

Use Bastion drones so you can deal damage without aiming or stepping out of position.
STEP 7/9
Let zombies stack at the invisible wall

Hold the spot while zombies pile up near the fence instead of reaching your character.
STEP 8/9
Swap to Celestial if you have it

Use Celestial for stronger Space Bomb damage once drone damage starts falling behind.
STEP 9/9
Add turret spam

Spawn turrets to help drones clear waves faster while you stay on the ledge.

Best classes and abilities for the fence ledge
| Class or ability | Use |
|---|---|
| Bastion drones | Accessible damage option for holding the ledge without using a gun |
| Celestial class Bombs | Better scaling damage when drones start feeling weak after a few hundred waves |
| Turrets | Extra wave clear when you can place them while staying tucked in |
Bastion is the easiest fit because drones keep firing while your character stays still, which is exactly what this ledge needs. Celestial is stronger later because Space Bombs hit harder, while turrets add extra clear speed when you can place them without moving out of position.
Do not treat solo Horde Rush on Nightmare with Glass Frenzy active as a farm requirement for this ledge. This route uses the Tundra fence ledge setup, not Horde Rush, Nightmare, Glass Frenzy, or a 30% Credit gain multiplier setup.
Patched Tundra spots to stop trying
| Old spot | What changed |
|---|---|
| House chimney, bookshelves, and windows | You can no longer stand on the chimney or bookshelves, and the window climb no longer works. |
| Cliff-edge hang spot | The ledge that let players hang off the cliff was removed before it became useful. |
| Shed-back ledge shelter placement | The character can no longer get close enough to the wall to place the shelter behind the shed. |
| Wall shelter clip | The shelter can no longer be placed inside the wall to create the old untouchable pocket. |
These were stronger than the current fence ledge, especially the shelter-in-wall setup, but current servers block the placement or remove the standing surface. If an old server still allows one of them, use it only while that server lasts and expect it to disappear once the server updates.
Mistakes that break the Tundra fence ledge

The biggest mistake is pulling out a gun. The spot is narrow, and the weapon stance can shove your character off the ledge, which is why drones, turrets, and Space Bombs matter so much here.
Standing too far away from the fence edge also ruins the setup, because the whole trick depends on staying tucked behind the tree and collision line. Old shelter clips are a separate problem: they can still appear in outdated servers, but they are not the current Tundra method.
Refresh this farm after every patch. Tundra ledge and corner safe spots change quickly, and this fence ledge route needs a fresh run whenever the map gets updated.
