Coreshatter

An idle tower-defense roguelite that respects your time.

One Core, one collapsing Grid, and waves pouring in from every angle. You build the Core that guns them down, push each run as deep as you dare, then Shatter to bank the haul. Here, death is the bank: you keep every run’s haul.

A deep Coreshatter run mid-firefight: the Core unloads on 360-degree waves as the bank fills
  • 8 Glyph slots
  • 7 ranked leagues
  • 3 meta trees
  • 360° waves
  • Real offline progress

Defend. Draft. Shatter. Converge.

Four verbs you’ll know in a minute and still be mastering in a month. Every run is a fresh build and a fresh gamble.

  1. 01

    Defend

    Your Core fights on its own, unloading everything you’ve socketed into a 360° storm. The bigger calls are yours: read the board, feel the FRONT close in, and choose how deep to push before you Shatter.

  2. 02

    Draft

    Every run deals a new hand. Draft Glyphs, slot Chips, and chain Circuits into a Core that plays fresh every run. Reshape the whole build for free, because today’s winning build becomes tomorrow’s puzzle.

  3. 03

    Shatter

    Cash out the second the run is worth it. Shatter to lock in your Scrap and Data for keeps and come back stronger. Push too far and breach? You still bank it all. Death is the deposit.

    Converge

    Hit Convergence for permanent power you keep forever, starting in your very first session. Every reset relaunches the loop from a higher floor, and the numbers start going vertical.

A deep Coreshatter run mid-firefight: the Core firing on all sides as projectiles fill the arena

Socket eight Glyphs. Fire them all at once.

Stack up to eight Glyphs and they all open up together: fans, beams, orbits, and drones layering into one screen-filling barrage. The deeper your build, the more the arena vanishes under your own firepower.

Hundreds of fusions
Merge two Glyphs into a named hybrid that fires in a way only the fusion can.
Set archetypes
Complete a set and the whole run reorganizes around one devastating bonus.
Tuned to you
Build for raw damage, for survival, or for pure chaos, then Shatter when the screen can’t hold any more.

Idle that plays fair.

This idle game earns every minute you give it.

Real offline progress
While you’re gone, your Core keeps mining and your best build keeps running. You come back to a real, itemized payout, ready the moment you open the app.
Endless variety
Run affixes, hundreds of Glyph fusions, and Circuit synergies open a huge space of viable builds. Every run is a fresh puzzle with more than one answer, and the deeper you go, the more the meta opens up.
Money buys time
Opt-in rewarded ads, the one-time Ad-Free Boost (removes ads and adds a permanent yield boost), Flux packs for cosmetics, the Season Pass, and the monthly Mainframe subscription all buy speed or style, never a wall key. Every wall in the game is reachable for free; you spend to get there faster.
A snowball meta in 30 minutes
Three upgrade trees snowball fast, the Foundry, the Mainframe, and the Codex, all earned by playing. Your power spikes hard inside the first half hour.

Climb to Grandmaster.

When you’re ready to prove it, two ladders run a real ELO climb through seven leagues, Bronze to Grandmaster, on a fresh shared challenge every day.

Aegis Trials
Everyone pilots the exact same daily kit, so the only variable is you. Pure skill, and anyone can reach the top.
Ascendant Ladder
Bring the deepest build you’ve forged and throw it at the entire field.

Place into a league, climb the live Standings, and chase the dual-rank capstone for the few who top both. Seasons wipe the slate every six weeks, and season rewards are cosmetic.
