CORE: Idle Tower Defense

Build the ultimate tower and survive endless waves in CORE, an idle tower defense and auto shooter with deep upgrade strategy.

A single glowing Core stands at the center of the arena and fires automatically. You don't aim and you don't dodge — you make the decisions. Spend Credits, shape your build, choose Perks and see how long your tower can hold.

★ UPGRADE WITHOUT STOPPING THE FIGHT
Every kill earns Credits. Spend them at any moment on Damage, Fire Rate, Range, Crit, Health, Credits per Kill and more. The battle keeps going and every upgrade applies instantly, so each second is a strategy decision.

★ GAME-CHANGING PERKS
Every 10 waves, pick 1 of 3 powerful Perks: extra projectiles, pierce, chain lightning, overdrive trade-offs and defensive transformations. Every run becomes a different roguelike tower defense build.

★ PERMANENT PROGRESSION
Bring home Cores after each run and invest them in the Workshop and Research. Your next tower starts stronger, lasts longer and pushes into harder Sectors. Satisfying incremental growth — progress never feels wasted.

★ CORE SYSTEMS
Unlock late-game abilities like Orbital Array, Chain Arc, Pulse, Gravity Well, Beam Array, Mine Ring and Seeker Array and turn your Core into an automated weapons platform.

★ GEOMETRIC ENEMIES, ELITE THREATS AND BOSSES
• Basic — marches straight at your tower
• Fast — low health, rushes in
• Tank — huge health, resists knockback
• Ranged — stops at range and shoots back
• Splitter — breaks into three shards on death
• Protector — shields nearby allies
• Charger — telegraphs a line, then dashes
• Boss — summons escorts and raises shields as it weakens
• Ray Elite — charges a line, then fires a heavy beam at the Core

★ SECTORS, MILESTONES & BOSS FIGHTS
Climb through escalating Sectors, claim one-time Milestone rewards and face bosses that test every part of your defense.

★ PLAY YOUR WAY
Let your tower defend itself while you take a quick break, or optimize every Credit and target priority for a record run. Short sessions, deep strategy.
