HOW TO PLAY
OBJECTIVE
Defend your base by intercepting incoming missiles before they hit the ground. You start with 100 Health, and each missile that hits the ground deals 10 damage. Reach 0 Health, and it's Game Over. Survive waves, rack up points, and clear levels to climb the leaderboards.

SCORING & COMBOS
Every intercept above 20m scores base points. Combo: Chain intercepts within 3 seconds to build a multiplier (+0.25× per hit, up to ×10 maximum). Bonuses:
• Altitude: High-altitude hits scale up to 3× points (maxes at 100m).
• Clutch: Low-altitude hits under 35m grant a 1.5× bonus.
• Long Range: Hitting a target more than 50m away horizontally gives a 1.2× bonus.
• Angle: Shallower angles score more (1.5× at 30°), while steep angles score less (0.75× at 70°).
AEGIS RECOVERY PROTOCOL (LEVEL 3+)
From Level 3 onwards, you gain access to the Aegis Defense Gauge (cyan bar below your launcher). Fill it to 100 Energy to trigger an Aegis Payload, restoring health and deploying defenses. Energy is gained exclusively through active, skillful gameplay:
• Low-Angle Kills: Intercepts below 45° angle (+10)
• High-Altitude Kills (L5+): Intercepts above 70m (+5)
• Combos: Hitting 3x and 5x chain milestones (+10/+25)
• Near-Misses (L4+): Interceptors flying dangerously close to targets (+5)
• Scrap Recycling (L8+): Catch falling Scrap Orbs from 4x combos (+40)
• Event Missiles: Courier hits (+35), Medic hits (+100)
Payloads: Base heal (+20). At Level 7+, deploying Aegis also activates a global horizontal shield that absorbs one missile impact. At Level 10+, Aegis can overheal you up to 150 (gold health) and acts as an EMP Last Stand to save you from a lethal blow if the gauge is half full.
LEVEL COMPLETION (CAMPAIGN & DAILY)
To advance, you must hit three thresholds: a minimum Score, a minimum Intercept count, and a minimum number of Waves survived. Once all three are met, a 3-second countdown begins — then the level clears automatically. No need to wait for a specific wave phase.
LEVEL SELECT — ENDLESS SURVIVAL MODE
Level Select works differently from Campaign. You pick an unlocked level and survive indefinitely — there is no advance. Your score climbs as long as you live, and that is your personal best for that level. To unlock the next level: meet all three criteria at least once during your run. When you die, the next level unlocks and appears in Level Select. You never need to replay earlier levels just to access a harder one.
MODES
Campaign — A full run starting from Level 1 with random spawns. Ranked on the All-Time leaderboard. Daily Challenge — Every player faces the exact same deterministic missile pattern for the day. Features daily modifiers (Speedrun, No Radar, or Precision). You get one ranked attempt per day before it locks to unranked practice. Resets at midnight UTC. Level Select — Endless survival on any unlocked level. Your best survival score per level is tracked on the Level Runs leaderboard. Meeting all criteria unlocks the next level.
