Coreshatter: Idle TD Roguelite
Tower defense, draft, prestige
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
The endgame just opened up. Unlock the Trove, hunt and forge Vestiges, stake your Axioms in Gambit, and see new looks for eight Glyphs.
Defend the Core. Draft Glyphs. Shatter to bank, Converge to begin again.
Coreshatter is a chill idle tower defense roguelite built for the long game. Lay out a defense, read the waves crashing against your Core, and tune a build with genuine depth. Then prestige and push deeper. It keeps playing while you are away and pays out when you return, so a quick check-in and a long strategy session both feel good.
THE CORE LOOP
- DEFEND: Enemies stream across the Grid toward your Core. Your Glyphs fire on their own while you read the fight and steer the run.
- DRAFT: Every run deals a fresh roguelite hand. Choose Glyphs and Chips, chase synergies, and adapt to each wave.
- SHATTER: Bank the run's spoils and lock in your gains.
- CONVERGE: Prestige to reset with permanent power and open deeper systems each time.
DRAFT AND BUILD
- Socket Glyphs and Chips into a board loadout where placement changes everything.
- Find synergies across offense, defense, and economy pieces.
- Answer wave modifiers that reward a flexible, adaptable build.
- Auto-arrange your board, or hand-place every piece for full control.
WAVES THAT TEST YOUR BUILD
- Face a roster of distinct foes, from swarming Motes and splitting Splitters to shielded bruisers and Corruption bosses that demand an answer.
- Each wave can shift the rules, so the run that beats one seed may stumble on the next.
- Endless escalation rewards builds that scale.
DEEP PROGRESSION
- Invest Scrap, Data, and Flux across the Foundry, Mainframe, and Lattice upgrade trees.
- Build a network of up to 8 linked Cores, each with its own feel and bonuses.
- Collect and master Glyphs in the Codex and chart your growth in the Constellation.
- Convergence prestige compounds your power run after run.
THE ENDGAME OPENS UP
- Complete the Axiom tree to unlock the Trove, then hunt, forge, and equip Vestiges: collectible relics, each with a passive that reshapes a run.
- Deep Hunts: push a run past wave 100 to recover a Vestige's Fragments and forge it toward Apex.
- Research: a permanent Core upgrade tree.
- Gambit: stake earned Axioms on a live run, hold past the floor and Shatter for a bigger payout, or breach and lose the stake.
RANKED LADDERS
- Take it online with a new competitive endgame: climb a daily ELO ladder from Bronze to Grandmaster.
- Aegis Trials hands every pilot the same curated daily kit, so your rank comes down to pure skill.
- The Ascendant Ladder pits the build you have forged against the whole field.
- A fresh shared challenge every day, six-week seasons, and a live Standings board you can climb. Rewards are cosmetic.
IN-RUN AGENCY
- Call Reinforcements when the pressure spikes: REPAIR to patch your Core, HOLD THE LINE to dig in.
- Make the clutch draft pick that turns a losing run around.
- Light, deliberate decisions you make in a tap.
IDLE AND OFFLINE
- Offline progress that matches live play, so time away is never wasted.
- Auto-Run keeps earning in the background while you plan your next build.
- Made for a few minutes a day or a long tuning session, your call.
BUILT TO PLAY YOUR WAY
- Colorblind-safe coding that reads by shape and label as well as hue.
- Reduced-motion support, scalable text, and a high-contrast interface.
- A calm, flat interface with the light and motion saved for the arena where the action lives.
Free to play. Set up your defense, Shatter, Converge, and see how deep the Core goes.
