Coreshatter: Tower Defense

Coreshatter is an idle tower defense roguelite. Enemies close in on your Core from every side, and your Glyphs fire on their own. You pick the build at each Draft and choose when to Shatter.

THE RUN
- Drafts offer Glyphs (weapons) and Chips (stat upgrades). Place the right Chips side by side to form one of 23 Circuits.
- Fuse two Glyphs into one of 451 Fusions.
- Heat rises over time and with each kill. At 100% Heat, the run ends (Heat peak). Each Draft has one free re-roll, and more cost Heat.
- The Front is a line that closes on your Core. If it gets there or the Core's integrity runs out, the run ends. HOLD pushes the Front back and REPAIR restores integrity. Both spend the run's Scrap.

ENEMIES
- 31 enemy types: Motes swarm, Splitters split when killed, Wardens carry shields, and Corruptors and bosses speed up the Front.
- Each run rolls a modifier that changes the enemy mix, so the best build changes too.
- From wave 50, an ultra boss with its own attack spawns every 25 waves.

WHAT YOU KEEP
- Every run banks its Scrap and Data, however it ends. Shatter to end it yourself. In standard runs, it adds up to 25% bonus Scrap.
- Converge to prestige. Reset with permanent power, and unlock more Cores, Strain and Reformat as your Convergences add up.
- Converging pays Shards for Lattice upgrades. Reformat also clears your Shards and Lattice upgrades and pays Axioms, which buy permanent Axiom rules.
- Unlock up to 8 Cores and play one per run. Each has its own Keystone (a trade-off you can swap for free), Core Law and Strain levels. Link Cores on the Core Map to raise their away income.

STRAIN, CRAFTING AND CORE LAWS
- Strain: from your first Convergence, each Core has eight levels, each adding a harder rule. Clear one by reaching its target wave and Shattering. First clears pay rewards.
- Crafting: build your own Glyphs from parts earned in Strain. Choose how each one fires, fill its sockets and forge it.
- Core Laws: turn on a Core's Law for an effect with a cost, such as a shockwave around the Core after every 10 kills near it, for 15% less Glyph range.

THE ENDGAME
- Buy every Axiom rule to open Vestiges: relics you forge from Fragments and equip for a passive bonus.
- Hunt a Vestige to earn its Fragments from each boss you kill from wave 16 on and from runs that reach wave 100. Forge it again to raise its rarity toward Apex.
- Garrison Vestiges on Cores for more away income, and attune them through ten tiers to raise their bonus.
- Gambit: stake Axioms on a run. Clear the target wave, then Shatter to get them back plus a payout. Any other ending loses them.

RANKED AND LIVE EVENTS
- Ranked has two modes, each with seven leagues and three matches a day. Aegis Trials give everyone the same daily Glyphs, Fusions and Chips. In the Ascendant Ladder, you bring your own upgrades.
- Grid Season is a monthly reward track. Clearing waves moves you up it.
- Anomalies are timed events that change enemy spawns and pay Axioms, Fragments and Flux for set goals.
- Once a day, your first run that clears 50 waves earns bonus Flux.

IDLE AND OFFLINE
- While the app is closed, Auto-Run earns Scrap and the Mainframe mines Data. Both bank when you return.
- Automation can pick Draft cards, Shatter and claim Research (timed upgrades) for you.
