[YETI] Survive Zombie Arena
Your first steps before a match
StepBefore you play your first wave, there are a few things to sort out in the lobby. Codes give you free Credits and bonuses, so skipping them costs you real progress.
- Open codes
go to the Shop icon on the left side of the lobby, find Redeem Codes at the bottom, and enter each code exactly as written, matching uppercase and lowercase letters.
- Start as Survivor
it is free, and it is fine for your very first run while you decide where to spend your first Credits.
- Set your first upgrade goal
the Marksman class costs 15,000 CR and should be your first major purchase, so keep that number in mind from the start.

Weapon progression through a run
Step
Zombies get stronger as the waves climb, so your weapon needs to keep pace. The basic upgrade path is handgun first, then shotgun before elite zombies appear, then rifles for mid-game stability. Inside a match, you spend Crystals to unlock higher weapon slots: Slot 2 costs 150 Crystals, Slot 3 costs 750, and Slot 4 costs 2,500. Slot 4 weapons are the endgame priority and can cost millions of Credits.
- Buy the shotgun early
elite zombies hit hard, and you need the shotgun in hand before the first elite shows up, not after.
- Move to a rifle
rifles let you control crowds from mid-range and stabilise your damage for the tougher middle waves.
- Target Acid Spitter (175,000 CR)
its damage-over-time effect makes it a solid stepping stone toward the top-tier Slot 4 weapons.
- Work toward Gumdrop Blaster (500,000 CR)
the slow effect on enemies buys your team breathing room.
Slot 4 endgame weapons
TableOnce you can equip Slot 4 weapons, your choice determines how far into the later waves you can push. Some are bought with Credits at the Armory; others drop from bosses or come out of crates.
| World Ender (3,500,000 CR, Armory) | its special attack charges after 30 kills and clears large groups at once |
| Ban Hammer (Guest 666 drop or Retro Crate) | base crowd DPS 76,363; its passive summons Noob minions after every 40 kills, and crowd DPS scales to 162,909 at max upgrade |
| Frost Dagger (Yeti boss drop) | Slot 4 weapon that launches up to 15 aimed icicles in a backflip attack; obtained only from the Yeti |
| Arctic Striker (1,000,000 CR) | freeze effect causes enemies to take one and a half times more damage |
| Soul Cannon (Pirate Chest only, Slot 3 Mythic) | DPS 163,636, obtained by opening Pirate Chest |
Class choices and what they do
TableEvery class unlock is permanent once purchased. Each class fills a different role, so a team with a balance of damage, defence, and healing survives further than one stacked with the same class.
| Marksman (15,000 CR) | the best first unlock; its Deadeye penetration skill punches through a whole line of zombies in one shot |
| Medic (10,000 CR) | cheapest support option; heals both players and structures, making it very strong in a coordinated team |
| Tactician (75,000 CR) | places barricades and turrets to lock down corridors; pairs especially well with Medic |
| Bastion (250,000 CR) | deploys a shelter that makes the whole team invincible and regenerates HP, with a laser turret and combat drones as additional abilities |
| Necromancer (250,000 CR) | Death Nova detonates all active minions at once for massive area damage, making it dominant in late waves |
| Overclockr (250,000 CR) | supercharges turrets and minions and can freeze time for enemies |
Difficulty modes and Credit rewards
Summary
Three difficulty modes are available, each paying out more Credits per kill. Nightmare has one additional twist: waves run continuously without a purchase phase between them.
- Normal
5 Credits per kill; unlocked from the start; 1% Bloodmoon Zombie chance
- Hardcore
7.5 Credits per kill; unlocked by reaching Wave 25 in Normal; tougher zombies and 1.25% Bloodmoon Zombie chance
- Nightmare
12.5 Credits per kill; unlocked by reaching Wave 100 in Hardcore; faster and more brutal zombies, 1.5% Bloodmoon Zombie chance, and waves start automatically with no purchase phase between them
Purchase phase and Auto Skip
WarnBetween waves you enter a purchase phase where you buy weapons, place defences, and upgrade. Auto Skip shortens this phase by starting the next wave early. Because zombies scale up in health and damage as waves progress, going into a wave underpowered is the most common reason teams wipe.
Zombie types worth knowing
SummaryThere are 20 zombie types across three categories. Some only appear on specific maps, and others are summoned by bosses rather than spawning naturally. Raids cap at five waves, which cuts out many of the harder zombie types — though bosses in Raids can still summon their own variants of those zombies.
- Main zombies
standard enemies that appear across normal play; Runner and Decayed can spawn as early as Wave 1 in Raids
- Map exclusive zombies
only found on their specific map; Pirate Deckhand and Pirate Swordsman appear on Pirate Cove, and Pumpkin Minion appears inside Abandoned Castle
- Summoned zombies
spawned by bosses such as Guest 666 rather than appearing on their own
- Raids-only limitation
Ashwalker, Pirate Gunner, Shade, Explosive, Pirate Skeleton, Flyer, Blood Zombie, Pumpkin Guard, Howler, Volatile, and Electro do not appear in Raids because of the five-wave cap; however, bosses such as Flying Dutchman and Yeti can still summon their variants of those zombies
- Two-zombie waves
Shade and Explosive both appear on Wave 20 on any map; Pirate Skeleton and Flyer both appear on Wave 25 if Pirate Cove is chosen
The Yeti boss
Check
The Yeti is a recurring boss that appears on a fixed schedule across most maps. It has a stronger form called the Ultra Yeti, and it can drop a unique Slot 4 weapon.
- The Yeti spawns every 75 waves on every map except Crossroads
- The Ultra Yeti is a stronger version with higher drop rates for weapons the Ultra Hunter gamepass doubles the chance of encountering it for everyone in the match
- Defeating the Yeti gives a low chance to drop the Frost Dagger, a Slot 4 weapon that launches up to 15 aimed icicles
- The Yeti does not damage player-built structures, barricades, or Necromancer minions
Artifacts system
CheckArtifacts were added on July 19, 2026. Each one gives a passive stat bonus and a unique ability. Rolling is the main way to obtain them, and a ceiling guarantees a Legendary-rarity Artifact by your 50th roll. Exclusive Artifacts from events or the battle pass cannot be obtained from the standard crate.
- Each roll costs 100,000 CR at the Artifacts Crate
- Your 50th roll is guaranteed to produce a Legendary-rarity Artifact regardless of earlier results
- Artifacts now have a fourth equipment slot
- Exclusive Artifacts such as the Pirate Wheel and Pirate Crow come from events or the battle pass, not from the standard crate
- The Lucky Coin Artifact gives a 20% chance to collect event currency twice per drop
Earning Credits without spending Robux
TipsAll classes and weapons purchasable at the Armory are available with Credits, which you earn by killing zombies.
- Redeem every available code in the lobby before each session.
- Use Marksman's penetration skill to hit multiple zombies per shot.
- Once your equipment is strong enough, switch to Hardcore or Nightmare difficulty
Hardcore pays 7.5 Credits per kill and Nightmare pays 12.5, compared to Normal's 5.
- When an event is running, prioritise killing event zombies to collect event currency alongside your regular Credits.
- Equip the Recycler Artifact for a 20% chance at bonus Credits on every kill or assist.

Common questions
FAQWhere do I enter redeem codes?
In the lobby, click the Shop icon on the left side of the screen, then find Redeem Codes at the bottom of the menu. Type the code exactly as you see it — capitalisation matters — then press Redeem to collect your reward. Each code works only once per account.
What class should I buy first?
Marksman at 15,000 CR is the strongest first purchase. Its Deadeye penetration skill lets you hit a whole line of zombies with one shot.
Can I unlock everything without spending Robux?
Every class and all weapons sold at the Armory are purchasable with Credits, which you earn from kills alone. Redeeming codes gives you a free Credit boost, and switching to Hardcore or Nightmare once you are ready pays out higher kill rewards. Exclusive Artifacts from events require participating in those events.
Why did my team wipe right after Auto Skip?
Auto Skip starts the next wave the moment the vote passes, giving anyone still shopping no time to finish. If your weapons were not upgraded before the wave started, the enemy health scaling overtakes your damage output almost immediately.
Which Slot 4 weapon should I aim for?
World Ender at 3,500,000 CR is the main free-to-play end goal — its special attack clears large groups after every 30 kills. On the way there, pick up Acid Spitter at 175,000 CR for its damage-over-time effect, then Gumdrop Blaster at 500,000 CR for its enemy-slowing bonus. Arctic Striker at 1,000,000 CR has a freeze effect that makes enemies take one and a half times more damage.
When does the Yeti boss appear, and how do I prepare?
The Yeti spawns every 75 waves on every map except Crossroads. It does not damage player-built structures, so defensive setups with barricades and turrets remain intact during the fight. The Yeti has a low chance to drop the Frost Dagger, and the Ultra Yeti variant drops weapons at a higher rate.
What is the Bastion class price?
Bastion costs 250,000 CR. It deploys a shelter that makes the whole team invincible and regenerates HP while inside, and it also has a laser turret and combat drones as additional abilities.
