Survive Zombie Arena: How to AFK Farm With Every Working Glitch

Farming credits and Void Shards in Survive Zombie Arena gets far faster once you stop fighting waves head-on and start standing where zombies simply cannot reach you. The reliable exploits fall into three buckets: safe-spot positions that break zombie pathfinding, high-jump launches onto rooftops using the Bastion class Shelter, and clips that drop you under the map for near-instant wave clears.

Quick answer: Equip the Bastion class, buy a Shelter for 1,000 crystals in-round, place it flush against a wall or pillar, enable shift-lock, and repeatedly jump in and out to launch onto a roof — or wedge into a narrow ledge or barricade where zombies crowd below but land zero hits.

What you need before farming

The Bastion class is the backbone of most of these exploits because of its placeable Shelter gear. Bastion’s kit also includes a Laser Turret and a Drone, both of which keep dealing damage while you sit still. Necromancer is the strong second pick, since its Soul Harvester and Raise Undead abilities summon minions that fight for you on maps like Rooftop Siege.

Requirement	Detail
Class	Bastion (Shelter high-jump) or Necromancer (summon defense)
In-round gear	Shelter costs 1,000 crystals; place it before attempting the jump
Controls	Shift-lock must be enabled for high-jumps and under-map clips
Avatar scale	Keep it small — oversized avatars fail the tight clip glitches

Shelter high-jump glitch

This is the core trick for reaching rooftops and other high surfaces zombies can never climb. It works on Rooftop Siege against the concrete pillar and on Abandoned Farm against a tree.

Survive early waves until you bank 1,000 crystals, then buy the Shelter gear.

Place the Shelter directly against a vertical surface — a concrete pillar on Rooftop Siege or a tree trunk on Abandoned Farm.

Enable shift-lock, then step into the Shelter.

Jump in and out of the structure repeatedly against the wall. Each cycle builds upward momentum until you launch onto the roof or the tree’s collision box.

Once you land on top, zombies have no path up. You can shoot down freely or let your Bastion turret and drone clear the crowd while you AFK.

Safe-spot positions that break zombie pathfinding

Several map locations sit on narrow collision boundaries where zombies path toward you but can’t finish the route. They pile up nearby, walk away, or gather on the wrong side of the room, leaving you unharmed. These need no gear beyond a decent weapon.

Map	Spot	How to hold it
Rooftop Siege	Staircase railing	Stand on the thin outer railing of the main staircase; zombies crowd below but can’t climb it.
Rooftop Siege	Helipad sandbags	Wedge into the sandbag pile on the helipad to block most pathfinding.
Atlantis	Light fixture ledge	Jump off the upper platform onto the wall-mounted light; zombies get stuck on the adjacent stairs.
Atlantis	Pillar beam corner	Shift-lock, hug the vertical pillar, and jump onto the outer edge of the horizontal beam.
Abandoned Farm	Silo back wall	Stand on the grass line flush against the back of the red silos to fail zombie pathing.

Note: On the Atlantis beam, only the outer corner is safe. The first section of the beam still lets a zombie walk up and hit you, so position tight into the corner before you go idle.

Under-map and out-of-bounds clips

The strongest farming comes from leaving the playable area entirely. Below the map, the game’s spawn system misbehaves and enemies die on spawn, which is the fastest way to clear waves while completely idle.

Abandoned Farm under-map slip

Find the small dirt gap near the outer wall boundary of the map.

Slide into the gap while moving forward.

Toggle shift-lock on and off repeatedly until you slip beneath the floor terrain. From under the map you can shoot zombies safely from below.

Rooftop Siege wall clip and infinite farm

Farm credits and buy the Void Scythe (about 2,500 credits), then move behind the helipad structure and face the grey wall.

Swing the Void Scythe repeatedly into the wall. The attack animation’s forward momentum clips your avatar through the collision into the hollow interior beneath the rooftop.

With Necromancer equipped, cast Soul Harvester and Raise Undead. Your skeletons spawn above and fight the zombies while you stay untouched inside the building.

For the deepest farm, walk to the interior edge and drop into the void between the buildings. You land on a sandy floor far below the map, where zombies spawn in mid-air and instantly die. Waves clear on their own, so you can stand idle and rack up credits and shards.

On Prison Yard, there is also a simpler exit: walk into the corner fence near the trash can and clip through the collision boundary to reach the outside of the map.

How to confirm the glitch worked

You know a safe spot is holding when zombies stack up around your position but your health bar never drops. On the high-jump, you should physically land on top of the roof or tree with enemies pathing uselessly below. For the under-map and out-of-bounds clips, you’ll see your avatar pass through the floor or wall, and out of bounds you’ll watch enemies die the moment they spawn as waves advance without your input.

Why a glitch fails and how to fix it

Problem	Fix
Clip glitches won’t trigger (e.g. Prison Yard fence)	Your avatar scale is too large; use a smaller character body.
Shelter high-jump doesn’t launch	Place the Shelter flush against the wall and keep shift-lock on; re-place if there’s a gap.
Zombies still hit you on Atlantis beam	Move fully into the outer corner — the inner beam section is not safe.
Bastion shelter spot in a staircase	Expect a few placement attempts before it locks into the god-mode position.

For a shard-focused session, run Nightmare difficulty, since galactic zombies spawn more often there and drop the Void Shards you’re after. Longer runs pay out more than repeated short ones, so build a spot that survives dozens of waves and let the turrets, drones, or summons do the rest while you step away.
