Survive Zombie Arena: Every Working Glitch and Safe Farming Spot

Several spots in Survive Zombie Arena let you slip out of a zombie’s reach and keep farming crystals while the horde piles up nearby. Most rely on map geometry or the Bastion class Shelter, and they still work across the Abandoned Farm, Atlantis, and Rooftop Siege maps. The steps below cover how to trigger each one, how to tell it worked, and which older tricks are now patched.

Quick answer: On Abandoned Farm, walk into the dirt block next to the green tree in the fenced corner to clip underground; on other maps, place a Shelter against a fence or silo and jump off it to reach a safe ledge above the zombies.

What you need before starting

The Shelter-based glitches require the Bastion class, a Legendary Defense class whose kit includes Shelter (Rare), Laser Turret (Epic), and Drone (Epic). Select it from the Class menu before you enter a spaceship. The underground and corner spots do not need a specific class, only movement and a weapon to shoot upward.

You can start any run from a green spaceship in the lobby, then pick your map, difficulty, and party size before pressing CREATE. Load into the game through Survive Zombie Arena on Roblox if you are not already in.

Underground clip glitch on Abandoned Farm

This glitch drops your character into a hollow room beneath the Abandoned Farm map. Once inside, you can shoot up through the ceiling to kill zombies on the surface and collect crystals without being reached from ground level. It works on Normal, Hardcore, and Nightmare difficulty.

Spawn in and head to the circular fenced area with the hay bales. Find the corner of the fence next to the green blocky tree.

Walk directly into the specific dirt block in that corner. Your character will sink about halfway into the ground. Zombies can still attack and damage you while you are stuck at this stage, so do not stop here.

Equip your gun and hold W to push forward through the wall. The character clips fully through into the hollow area below the map.

Move through the narrow tunnel into the underground room. Aim upward and fire through the ceiling to hit zombies overhead. To add drones, look for the specific spot in the tunnel that allows spawning, then spam Q up to the 10/10 limit.

You know it worked when your view is fully below the surface inside an enclosed room and zombies stop landing hits. A few zombies may spawn underground, but they immediately glitch back to the surface. Once you have farmed enough crystals, you can buy the Void Scythe from the in-match shop for 2.5K.

Silo wall-climb glitch

The silo glitch puts you on an invisible ledge partway up one of the large red silos, out of reach of ground zombies. It uses the Shelter as a boost and needs a second player or alt account.

Stand next to the two red silos and place a Shelter flush against the wall of one silo.

Jump onto the Shelter, then jump onto the alt account’s head. This extra height lets you clip onto the side of the silo.

Land on the invisible ledge along the silo wall. When you are standing there without falling and zombies below cannot climb up, the glitch has taken. Drones deployed from this position clear the crowd below for you.

Shelter and fence sky glitch

This one launches your character onto an invisible barrier high above the map, where ground zombies gather below but cannot climb. It works best on a raised hill with a wooden fence.

Place a Shelter directly beside a wooden fence on the raised hill.

Press E to enter the Shelter, then press F to exit while spamming the jump key to land on top of the fence.

The character shoots up and settles on the invisible barrier high in the air. You can walk along it by following the line of fences below you.

Two things break this spot. Trying to deploy a drone during the fence jump can make you slide off, so wait until you are settled. Some fences have no collision barrier above them, and walking over those sections drops you straight back to the ground.

Atlantis AFK corner

Atlantis has a lower-level corner where zombies pile onto the platform above your head without being able to pathfind down to you. From there you shoot up into the crowd safely.

Run up the stairs to the upper platform, then walk along the narrow green metal support beams.

Jump from the platform onto the narrow ledge against the wall, then drop into the specific corner on the lower level next to the pipe.

Stay tucked in the corner. Zombies gather directly above but cannot reach you. Moving out of the corner triggers them to drop down and attack, so hold your position and fire upward or use drones.

Note: The old method of placing a Shelter inside the Atlantis staircase to clip through has been patched and no longer works.

Rooftop Siege AFK spots

Rooftop Siege has two dependable safe spots. The first uses a sandbag pile, which blocks NPC movement but not the player, so you can stand inside it while zombies crowd the outside.

Go to the helipad area with the piles of sandbags and walk straight into the middle of a pile. Your character model clips inside.

Deploy drones while sitting inside the sandbags. The zombies surround the pile but cannot land hits, and the drones clear them for you.

The second spot sits on the outer edge of the roof. Stand on the outer building wall or railing, then carefully drop down onto the tiny ledge just below roof level. Zombies mass at the edge directly above but cannot follow you down. An upward-swinging melee weapon such as the WorldEnd sword hits the whole crowd gathered above.

Note: The old ledge near the RPG spawn now has an invisible wall and can no longer be used.

Auto-attack trick without holding the mouse

You can keep firing or swinging continuously without holding the mouse button, which pairs well with any of the safe spots above.

Hold down the left mouse button to start attacking.

Press Escape to open the Roblox system menu, then release the left mouse button while the menu is open.

Press Escape again to close the menu. The character keeps attacking on its own with no further input.

Patched spots to avoid

Map	Old spot	Current state
Atlantis	Shelter inside the staircase	Patched, does not clip through
Rooftop Siege	Ledge near the RPG spawn	Blocked by an invisible wall

Map glitches like these tend to get fixed as the game updates, so a spot that works today may be walled off after a patch. If one stops clipping or a ledge suddenly has collision, treat it as patched and switch to another spot on the list rather than repeating the same input.
