Choose a 10-wave short run or NORMAL. Build two ARROWS beside the road. The shaded ground shows covered road tiles, not guaranteed safety. Press START WAVE. Add CANNON for crowds or FROST for fast enemies, and upgrade useful posts. The short goal is ten waves; the standard goal is thirty. You do not need every menu on day one.

Before each wave the scouts hand you imperfect intel. Call it right and you are paid gold plus an archetype counter for that wave. Call it wrong and you learn something about your patience. Passing is free: the streak holds and your grade only counts the reads you actually attempt. The Daily always reads. This is the whole point of the game: stop being surprised. The long form lives in the library, free.

TOWER MIGHT is a useful first damage upgrade. Add castle health if leaks end your runs, or starting gold if the opening is slow. Start a LAB project: cleared waves advance research, closed time does not. Forge levels help future casual runs, but ascension resets most of them. Cards, research and unlocks survive that reset. The Daily ignores permanent upgrades for a fair comparison.

Win at your top rank and the next one opens. The law never changes. Each rank makes enemies 32% tougher and a touch faster, and pays +5% bounty and +50% score and shards. Rank I starts gentle. Rank X stacks all ten mutators at once. Past X sits BEYOND, where the numbers climb without end and every rank wakes one of six rotating laws on top of the ten mutators. Climb when winning feels routine, not before.

Win the 30 and the run can keep going. Wave 100 seals the void. Wave 150 is the true floor, the campaign's last line. Hold it and the game offers you the way down.

Past wave 150, enemy pressure keeps growing. Earned resonance, echoes, doctrines and permanent upgrades support deeper castles. Echoes settle when the run ends and buy upgrades in THE DESCENT hall. Choose whether automation may descend; it is not forced. Wave 15,000 is the current cap, not a promised survival target. Depth seals record milestones and add their listed permanent effects.

VOID ASCENSION trades your shard bank and most forge levels for a permanent Void Star: +2% tower damage, +5% bounty, +10% shards, up to ten. Your best forge tracks survive as KEYSTONES, and cards, unlocks, research, and Chaos ranks all ride through. Ascend when the next star costs less than it pays. Early is fine. The climb back is faster every time, and star chests refill the purse on the way up.

VOID CARDS drop from every run that is not a Daily: waves 5, 10, 20, and 40, another on the win, and one more at 60. Duplicates level them. Five copies is L4, eight is L5, and dupes past max melt into shards or feed THE VOID CODEX for a permanent, self-taming bonus. Slot a deck before the run. More slots cost shards and pay for themselves.

Your VOID DOCTRINE decides what tower evolution does on that run: walls, tempo, economy, rot, storm, frost, single-target, or glass. Pick one in the loadout. Three are free, the rest are earned by feats or shards. The Daily always marches Warden's Road so everyone's score speaks the same language.

A LEGEND is a hero tower. Place it once per run, it levels itself every 4 waves with no gold spent, and its signature fires on its own from level 5. Let a level 7 legend claim 350 souls and it reaches APOTHEOSIS. Regular towers have their own summit: fully evolve a specialized tower and let it claim 250 souls of its own, and it transcends into its ★ PRIME form. Souls mean its kills, not yours.

The DAILY CHALLENGE gives every player the same seed: Normal difficulty, one recorded attempt, forge and Chaos upgrades ignored so scores compare cleanly. Missed a day? The last two stay open. No streaks, nothing lost. The VOID TRIAL asks five questions from the library and pays shards for right answers. The WEEKLY GAUNTLET turns with the ISO week: one Challenger seed, repeat all week · the deepest hold stands, score breaks the ties, and the board runs past 30: endless waves count. The EXPEDITION deals a random 8-tower hand · hit THIS WEEK and you and your friends race the exact same one.

Build help uses this run's gold and earned upgrades while the game is open. Browser suspension may stop execution; missed time is not reconstructed. Pause freezes the run. Closing earns no gold, shards, healing, research or waves. Breach ends the run and keeps results until Return to Menu. Night Watch and Eternal Engine ownership remain recorded as legacy investments, with no closed-time effect. No automatic refund or replacement has been applied. The v310 update & backups button in the footer explains the change.

One front per day, the same for every player, drawn from six: IRON SKY, GOLD WIND, SWIFT VEIL, STILL FRONT, LEAD FRONT, EMBER WIND. Each bends a run a little and most pay extra shards for the trouble. It rides normal, calm, endless, and queue runs · never the Daily, the Gauntlet, or an Expedition, and a race link carries its weather with it so a shared seed is always the same fight. The menu chip reads tomorrow's front too. Toggle it off any time; the void does not mind.

A road with no fixed shape, drawn fresh by a seeded pen every Monday at 00:00 UTC · the same road for every player for seven days. Nobody has practiced it, including the maker: one week where the read matters more than the routine. It joins the 🗺 MAP cycle after your first full 30-wave hold, takes weather like any road, and keeps its own records. If Monday turns while you are mid-run, nothing breaks: the exact road rides your run save.

Yes · ✏ THE CARTOGRAPHER, next to the map picker, opens after one full 30-wave hold. Draw the road leg by leg: straight lines or perfect diagonals, never crossing itself, 20 to 140 tiles, sealed at the castle door. SAVE & ARM puts it in your map cycle; COPY ROAD LINK hands it to anyone · the whole road travels as plain numbers in the URL. A road that arrives on a link runs once on your next run, and the Cartographer can ADOPT it for keeps. Race links now carry their ground too, so a shared seed is finally the same fight on the same road.

THE RE-KNIT. Deep below the floor · first at wave 225, then every 200th wave after · the void redraws the road between waves. It is telegraphed one wave ahead, never lands inside a tide, and is seeded by the run: the same seed knits the same roads, always. Towers the new road claims are refunded at full invested value, walls stranded on the dead road are paid out too, camps are buried where they stand, and your legend simply steps aside. The deep march stops being one kill box forever. Read the new ground; the gold in your purse is the apology.

A shorter run: hold 10, 16, or 22 waves on your usual setup, full pay per wave, a win screen at the end, no endless after. It is built for the minutes before a ranked queue. Win one and the screen closes with the ritual: four slow breaths, shoulders down, one intention, then queue.

VOID RATING ranks your lifetime reads · accuracy weighted by volume, DRIFTER to VOIDSIGHT, ten real calls to place, worn on the menu and every share. THE READ RANGE is where you raise it: ten drilled calls against seeded scouts, first drill each day pays +2◆ a hit, fifty calls a week opens a chest. The range even aims itself at the archetype you keep missing. Drills sharpen you; only real runs move the rating.

Every race link carries the sender's result. Open a friend's seed and their wave and score ride shotgun · the between-wave report shows the mark you're chasing, and the run-over screen calls the verdict: RIVAL DOWN or THE RIVAL STANDS. Same seed, same weather, no server, no excuse.

▶ WATCH THE WARDEN on the menu hands a full run to the machine: it builds, calls the reads, and chains the waves while you watch. Take the chair any time · every automation is an ordinary toggle, and your own idle settings return when the run ends. Fair warning, kept honest: the demo plays on your real ledger. Its wins and shards are yours, which is the whole idle covenant anyway.

There is. It is old. It expects arrows, and then two letters, and it pays once. People who grew up in arcades already know the whole incantation. The HALL OF RUNS keeps a title for whoever remembers.

THE TREASURY on the menu keeps the ledger. GOLD belongs to this run · towers, upgrades and repairs. VOID SHARDS are permanent earnings for the Forge, Lab and loadout unlocks. VOID ECHOES come from ending a Descent beyond wave 150 and buy six echo upgrades. VOID STARS come from ascension: trade the shard bank and most Forge levels for permanent power, up to ten stars. COMMANDER XP tracks your career. RESEARCH is completed knowledge, not a spendable currency: played clears add work to one paid project. CODEX INFUSION uses duplicate cards. SOULS are each tower's own kills · PRIME at 250, legendary apotheosis at 350. Gold is temporary. The other earned progress stays. Closing earns nothing.

THE CHARMWRIGHT deals twenty-four charms across four rarities for 30 void shards a pull · shards you earn by playing, never buy. The odds are printed on the door: 60% COMMON, 28% RARE, 10% EPIC, 2% MYTHIC, and every tenth pull without an EPIC forces the void's hand. Duplicates level what you own, up to level 5 at nine copies. Wear three at once; their passives · starting gold, damage, shards, rerolls, cheaper masonry · ride every casual run from the first wave. Never the Daily, so the fair fight stays fair. Nothing here costs money, because nothing here is for sale.

Four ages, and the menu names yours beside your next goal. EARLY GAME · THE FIRST HOLD: before your first campaign win; the whole job is holding all 30. MID GAME · THE CLIMB: wave 30 to the floor · chaos ranks, the forge, cards, endless past 100. LATE GAME · THE DEEP: the floor is sealed and the descent is yours · echoes, seals, your first ascensions. ENDGAME · THE FAR ROAD: wave 1,000 or three void stars, whichever confesses first · the long walk toward 15,000. Every share you post carries the age, so a Discord thread always knows who is speaking.

Splash answers MASS: cannon, mortar, scatter, the pyre when they bunch. Slows answer SPEED: frost, aurora, chrono, the gale when the column needs shoving back. Penetration answers ARMOR: railgun, ballista, voidspike, the execute for the finish. That is the grammar. Everything else in the arsenal is a dialect, and each button's one line tells you which. When in doubt, read the wave and buy the counter.

He is your hands on the field. Tap him, tap the map, he goes. VOID SLAM knocks the column back when it reaches him. Between waves he clears void camps and channels shrines, which is where the real wage is. Set the ⬥ AI to GUARD and he holds the final corner. Set it to HUNT and he pressures the front. A manual tap overrides the AI for five seconds, because the human is allowed to be right.

Every leak seeds a void camp, and camps buff future spawns until someone clears them. That someone is your jungler. Void shrines are the opposite: channel one in time and your towers hit harder for the rest of the run, permanently. Kills are rent. Objectives are property. Buy property.

Four kinds walk the campaign, and the name is the counter: MASS summons, SPEED surges, ARMOR shields, ABSENCE veils · hold the burst and strike the reform. Below the floor, named SOVEREIGNS hold every 250th wave with courts of their own. The orange ring is the telegraph · the ability is loading, so spend accordingly. And kill heralds first, always. That green circle is other enemies healing, and you are not paid to fight the same HP twice.

Every tower that survives 8, 20, and 40 waves evolves through three stages, and your doctrine decides what those stages do. Separately, at level 3 an attacking tower offers up to six forks: the two classics plus OVERCLOCKED, COLOSSAL, FARSEER, and GILDED. A fork is a promise, not a refund. Pick for the run you are in, not the run you wish you had.

Shard-unlocked specials that fire themselves during waves. DEATH WAVE sweeps the path. GOLDEN TOWER doubles bounty. BLACK HOLE drags the column into one apology. CHRONO FIELD slows the world. Slot one in the loadout and forget it: they cast on their own schedule, which is the point. Your hands stay on the reads. And when the ULT chip lights up, you may take the shot yourself · tap it or press U · or set ULT TIMING to BY HAND and own every cast.

You carry one reroll into every run: reject a dead perk offer, see a new one. Hit a 5-read streak and a second is banked · the hot hand earns agency. Streaks of 5, 10, and 20 stamp the screen, because a hot hand deserves witnesses.

One tap, one playstyle, never in the Daily. TURTLE opens tanky with cheap walls. WARDEN opens balanced: +25 gold, +1 castle HP. GLASS opens sharp: +8% damage on a thinner castle. Kits are training wheels with dignity. You will outgrow them and keep using them anyway.

Every kill a tower type has ever made is remembered. Each mastery level is +1% born damage for that type, capped at 50, never in the Daily. It is the slowest currency in the game and the only one you cannot spend wrong.

VOID ADAPTATION. Below the floor, any single tower type dealing more than half a wave's damage is blunted the next wave. The deep pays the whole arsenal, never one spammed answer. If your damage chart is one tall bar, the void is about to file a complaint.

Every 50th descent wave the tide rises: a telegraphed five wave modifier. Weather all five and the bonus echoes are yours. The telegraph is the mercy. Use it.

VOID PACTS are sworn mutators: a harder run, +10% shards each, never the Daily. The pact hall also holds TRIALS · Glass Castle, Heavy Purse, No Quarter, Silent Scouts · self-imposed vows worth +12 to 15% shards apiece. You are not paid for brave, you are paid for right. These pay for both, which is rare. Swear what you can keep.

Not live multiplayer: there are no servers or accounts. Instead, every player gets the same seeds. The Daily changes each day, the Gauntlet each ISO week, the featured Expedition each week. Every run ends with a share card and a race link, so a friend can play the exact seed. When the weekly leaderboard's backend is online, your best hold stands in that week's top 100.

TEMPO PROTOCOLS in the VOID LAB raise game speed step by step, all the way to 10×. Research ticks once per wave you clear. Speed is earned like everything else here: by playing.

Born SHINY. Rare, +5% damage, forever. It changes almost nothing. You will screenshot it anyway.

Every run pays commander XP, levels pay ranks, ranks pay rewards. The HALL OF RUNS keeps twelve wearable titles, FLOORBREAKER at wave 150 down to THE CASTLE THAT WOULD NOT FALL at 10,000, THE FAR SHORE at 15,000. Titles are identity, never power. Wear the one you bled for.

PAYS: shards and echoes fund permanent upgrades. POWERS: Forge levels, research, cards, charms, seals, stars and mastery improve a build. OPENS: towers, junglers, legends, doctrines, maps and Chaos ranks offer more choices. ADORNS: titles and avatars change your look, not your stats. Seeded challenge modes ignore some permanent bonuses so everyone faces the same test. THE TREASURY explains where each resource comes from and where it goes.

Start with shards from a run you can reliably finish. Buy the affordable improvement shown on the menu, then keep one Lab project paid while you play. Damage helps you kill; control gives it time; economy buys more towers; survival catches leaks. If you keep losing, inspect the defeat report before buying another damage level. Later, higher Chaos and deeper holds can pay more, but a slow failed push is not automatically a better farm. Beyond wave 150, Descent adds echoes. Compare earnings per played minute, not just the biggest payout. Repeat research is optional and respects your shard reserve. No spending happens while the game is closed.

Hold 30 on NORMAL. Improve your Forge, research and loadout. Push to wave 150 to open Descent and echoes. Wave 300 opens Warden build scripts. Ascension trades your bank and most Forge levels for a star; read the reset preview before committing. Ten stars, eleven depth seals through wave 15,000, five-level cards and specialized towers are finite milestones. Three existing Lab tracks now allow 500 levels each. The menu shows an affordable next step, a build-changing milestone and a longer ambition. They are goals, not promises that every build can clear them.

Start a paid Lab project, then switch REPEAT on if you want the next level bought automatically. KEEP SHARDS sets money aside for your other upgrades. Repeat follows that one project, waits if it would touch the reserve, and stops at the cap. Work comes from cleared waves while playing. Paused, saved, ended and closed games add no work. Completed research applies from your next run. Defeat leaves your results on screen; it never restarts.

A tower defense game that runs in your browser as one page, with no download or account. Read the incoming wave, build the counter, and hold the castle.

Yes. The whole game is this page. Your progress saves locally in your browser, and you can export it from Options at any time.

A standard hold is 30 waves. Choose FLOOR to push to wave 150, or DESCENT to allow the harder road beyond it. Strong builds can survive unattended while the browser permits this open game to run. A browser may freeze or discard a hidden tab; missed time is not caught up. The named seal ladder reaches wave 15,000, not an endless supply of handcrafted content. A breach ends the run and waits for Return to Menu.

Tilt is the frustration spiral after losing competitive games. This game is built as a reset between ranked queues: one calm run that rewards reading and patience, plus a coach review of your decisions before you queue again.
