// CORE FEATURES

• Endless citadel defense against escalating enemy waves
• Orbital weapon loadouts with pierce, splash, beam, and chain attacks
• Workshop upgrades across Attack, Defense, Utility, and Ultimate categories
• Permanent research powered by core shards for long-term progression
• Ultimate Array systems including solar bursts, stasis fields, gravity wells, arc storms, minefields, and more
• Defensive systems such as barriers, void mines, sentinel orbitals, plating, thorns, and regeneration
• Randomized starfield background with subtle pulsing stars and occasional meteor streaks
• Auto-upgrade support for hands-off progression during runs
• Automatic restart after citadel destruction with important run settings preserved
• Auto-save, manual save, load, import, and export support
• English and Korean language options

// HOW TO PLAY

1. Main Menu
Choose New Game to begin a fresh defense. Choose Load Game if you already have a save. Open Settings to change language, music volume, effects volume, or other play preferences.

2. Battle
Combat runs automatically. Your citadel and orbitals fire on incoming enemies while you watch health, wave pressure, gold income, shards, and upgrade timing. Survive as long as you can against scaling waves.

3. Workshop Upgrades
Spend gold during a run to improve damage, attack speed, critical hits, splash radius, range, defensive plating, regeneration, mines, barriers, sentinels, gold gains, and other systems.

4. Orbital Loadout
Add and improve satellite weapons around the citadel. Mix pierce, splash, beam, and chain orbitals to handle different enemy groups and wave pressure.

5. Research and Ultimate Array
Use core shards for permanent research and ultimate unlocks. Research strengthens future runs, while ultimate systems add powerful automatic effects such as stasis, storms, mines, gravity, and seeker swarms.

6. Defeat and Restart
If the citadel falls, the game can automatically restart the defense. Auto-upgrade state, speed, and current run preferences are preserved so the next attempt starts smoothly.

// TIPS

• Buy early damage and attack speed so the first waves do not overwhelm the citadel.
• Mix orbital types instead of relying on only one damage pattern.
• Use defensive upgrades before enemy contact damage starts draining the core too quickly.
• Invest in gold and shard growth if you want stronger long-term progression.
• Unlock ultimate systems once basic attack and defense scaling feel stable.
• Use auto-upgrade and speed controls when you want a more idle-friendly run.

// CONTROLS

Mouse / touch interface.
