How it works

Every run is a fight for the crossroads. The stronger your squad, the further it gets, and the more it earns.

01

Build your squad

Recruit riflemen, snipers, medics, guardians, rocketeers and engineers. Place six on the 5×5 grid and gear them up.

02

Hold the waves

Zombies come from every road, with a boss every tenth wave. Your squad fights on its own, and keeps going after you leave.

03

Earn $SUPPLY

Each wave pays, and higher waves pay much more. Spend it on stars, upgrades and depots, or take it out to your wallet.

Inside the fight

Six classes, a horde that grows every wave, depots that change the battle, and gear worth chasing.

Your squad

GuardianTank

Taunt: pulls nearby zombies onto himself. Soldiers next to him take 15% less damage.

RiflemanAll-rounder

Rapid Fire: doubles attack speed. Every 5th shot pierces to the zombie behind.

SniperLong range

Headshot: 4x damage to the toughest zombie in range. More damage the farther the target.

MedicSupport

Field Heal: heals every soldier nearby for 25% of their HP.

RocketeerSplash damage

Barrage: 5 rockets into the biggest crowd. Every 5th rocket leaves a burning patch.

EngineerCrowd control

Barbed Wire: slows a whole area by 50%. His shots chill zombies too.

The horde

Walkers, runners and brutes come down all four roads, more and stronger every wave.

A boss every tenth wave, with skills: Ground Slam, Summon Horde, Enrage, Toxic Spit and Armor Up.

Supply depots

GunshipMore damage for every soldier. It lifts off and circles the squad.
Field hospitalMore HP for every soldier.
Ammo depotFaster attacks for every soldier.
APC escortMore armor for every soldier.
Air strikeA jet bombs the biggest crowd on a timer.
GEAR

Six rarities

Common Uncommon Rare Epic Mythic Legendary. Loot drops in runs and crates; upgrade it, or fuse ten into a rarer one.

STARS

Merge and promote

Two soldiers of the same type and star merge into the next star, up to 5★. Stars boost every stat and what your squad earns.

WEATHER

Rain, fog and night

The weather turns every five waves and nudges the fight: rain slows the horde, fog shortens range, night makes them hit harder.

Built to be fair

Every payment is worked out on the server from how long your squad actually played. The page can't tell it what to pay.

  • Seasons with prizes. The top 50 of each season share the prize pool, sent straight to their wallets.
  • Daily quests and referrals. Extra $SUPPLY for playing every day and for bringing friends.
  • Dog tags and ranks. 41 achievements and a commander level from Recruit to Supreme Commander.
  • Eight languages. English, Spanish, Portuguese, Indonesian, Vietnamese, Russian, Chinese and Korean.

Questions and answers

The same answers you'll find in the game.

What is $SUPPLY?

The game’s token on Robinhood Chain. You earn it by holding off zombies, spend it on soldiers, gear and upgrades, and can withdraw it to your wallet. Prices and rewards are set in US dollars and convert to $SUPPLY at the live price.

How will $SUPPLY launch? Does the team hold any?

$SUPPLY will launch on Pons, a token launchpad on Robinhood Chain. The whole supply goes on sale at launch: no team share and no presale. The developer will buy about 300 USD worth at launch, in the same transaction that creates the token, to fund the leaderboard prize pool (10,000,000 $SUPPLY) and player withdrawals. Entry fees and Shop payments go to the game’s main wallet. The developer’s wallet addresses will be listed here at launch so anyone can check them.

What’s the difference between my wallet and in-game $SUPPLY?

Your wallet is on the blockchain and pays for Shop items (recruits, crates, 2x speed), the entry fee and deposits. In-game $SUPPLY is what you earn while playing; it pays for stars, merges, gear upgrades, fusing and depot perks. Deposit to move $SUPPLY into the game, withdraw to move it out.

How do I earn?

Every zombie can drop $SUPPLY, and bosses always do. Higher waves pay much more, so a stronger squad earns more. Tap the ⓘ next to Potential max wave to see what each wave earns.

Do I have to keep the game open?

No. With auto-restart on (Options), your squad keeps playing in a background tab and for up to 8 hours after you leave. Log in again to keep it going.

Why can’t I withdraw?

One of four things: free-trial earnings stay in the game until you pay the entry fee or buy something in the Shop; you’ve hit today’s daily limit; you’ve used up your lifetime withdraw allowance; or a withdrawal is still being checked. The Wallet shows which one.

What is the daily limit?

How much you can withdraw per day. It rises with your best wave (from 5 to 100 USD a day), with every starred soldier on your grid, and by 20% with 2x speed.

What is the withdraw allowance?

The total you can ever withdraw: your entry fee, plus your own deposits, plus a multiple of what you’ve spent in the Shop (0.8x up to 2.5x the more you spend), minus what you’ve already withdrawn.

How long do withdrawals take?

Each one is checked by our backend to stop bots, and usually clears within 24 hours. You get an on-chain transaction ID when it does.

What is the entry fee?

Your first 24 hours are free. After that, a one-time fee of 10,000 $SUPPLY (or 1 USD worth, whichever is less) keeps you playing. It counts toward your withdraw allowance, so you can take it back out later.

Why do I need ETH?

Robinhood Chain charges network fees (gas) in ETH. Keep a little ETH in your wallet for deposits, Shop purchases and the entry fee. Each transaction costs a few cents.

How do stars and merging work?

Two soldiers of the same type and star merge into the next star; the 5th star takes three 4★. Or pay for the star with in-game $SUPPLY. Stars boost every stat, your earnings and your daily limit, and most of the bonus sits on the 5th star.

What do supply depots do?

The buildings around the grid. Each gives the whole squad a boost (damage, HP, armor, attack speed or an air strike). Level 5 of any depot also adds +2% to your $SUPPLY earnings. Payments go to the main wallet and can’t be refunded.

How does the leaderboard work?

Ranked by highest wave each season. The top 50 split the prize pool, which starts at 1,000 $SUPPLY and grows by 5% of all spending in the game.

What are dog tags and commander level?

Dog tags are achievements: kill counts, wave milestones, 5★ soldiers, rare finds and more. Your commander level grows with kills, waves cleared and tags. Both show on your profile at the top left, and you can share them on X.

Can I try it before spending?

Yes. Turn on demo mode in Options: you get unlimited $SUPPLY to recruit, open crates, merge and upgrade. Nothing there is real, nothing you earn carries over, and you can switch back any time.

Can I lose money?

Yes. $SUPPLY’s price moves, the earnings shown are estimates rather than promises, and what you spend in the Shop or on upgrades isn’t refundable. Only spend what you can afford to lose.

Disclaimers

Please read these before you play or buy anything.

  • In development, testing with real money. HOLDOUT is a game in development. It now runs on Robinhood Chain with TESTSUP, a test token used before $SUPPLY launches. In the game, amounts show as $SUPPLY and are paid in TESTSUP, one for one. TESTSUP and ETH are real tokens: deposits, the entry fee, Shop payments and withdrawals are real transactions that cost network fees and can't be reversed. TESTSUP is a separate token from $SUPPLY and may never be worth anything. Only use small amounts you can afford to lose.
  • Not financial advice. Nothing on this site or in the game is financial, investment, legal or tax advice, or an offer to sell or a request to buy any token or security.
  • You can lose money. $SUPPLY's price can move sharply and can fall to zero. Earnings shown in the game are estimates, not promises. Purchases in the game are not refundable. Only spend what you can afford to lose.
  • Rules can change. Prices, rewards, limits, seasons and features can change while the game is developed. Withdrawals are subject to daily limits, a lifetime allowance and checks against bots, and can be delayed.
  • Blockchain risks. Transactions on Robinhood Chain cost network fees (gas) and can't be reversed. You are responsible for your wallet, its keys and its security. We will never ask for your seed phrase or private key.
  • Your local laws. You are responsible for making sure that playing and using crypto tokens is legal where you live. Don't play where it isn't.
