# Arc 2 — March 2026 Research Drop

## 📌 한 줄 통찰
> **"매 firepower → 매 mixed-tactic"**. 매 platform 의 damage-type 별 50% resistance 의 specialization. 매 single-unit steamroll 의 X — 매 mixed platoon 의 강제. 매 game balance design 의 modern lesson: 매 counter-class 의 explicit.

## 📖 핵심

### 매 patch 의 economics
- 매 Iridium (자원) 의 cost.
- 매 동급 research 보다 매 시간 short.
- 매 Operation: Western Sun 상점 의 unlock.

### 매 platform 의 specialization (50% damage reduction)

| 플랫폼 (new name) | 구 명칭 | Damage type 의 -50% |
|---|---|---|
| Support/Heavy Graviton | Airborne / Graviton | 매 ground unit |
| Support Insulated | Insulated | 매 AREA |
| Support Reinforced | Reinforced | 매 BURST |
| Support Armored | Armored | 매 SUSTAIN |
| Support/Heavy Aerojet, Heavy Clandestine | Flying/Floating Heavy | 매 air unit |
| Support/Heavy Resistor | Resistor | 매 status effect 면역 |
| Support/Heavy Bulwark | Plated / Bulwark | 매 flat damage reduction |

→ 매 attacker 의 single damage type 의 X. 매 mixed 의 forced.

### 매 신규 defensive structure

#### Metronomos Heavy Turret
- 매 15 level.
- 매 BURST damage.
- 매 fire rate 의 ramp up → "Flux Bubble" → reset.
- 매 high-HP tank 의 counter.

#### Nightwatch Bunker
- 매 10 level.
- 매 capacity 750 (대폭 ↑).
- 매 internal unit 의 range +20%.
- 매 infantry / vehicle / aircraft damage +10% 각.
- 매 radius 300 의 air unit 의 "Turbulence" (electronic warfare).

### 매 weapon balance
- **Warp Lance**: AREA 패턴 변경.
- **Deadeye**: splash 축소 + 단일 damage 의 increase.
- **Acid Rain**: split 거리 변경.
- 매 reliability 의 향상.

### 매 power 관리
- **Deep Reactor**: max 250 cap.
- **Fusion Tower**: max 450 cap.

### 매 Arc 2 unit 와 의 상호작용
- 매 Warlord Onymite (legendary infantry drone): 130K HP, 14K+ DPS, 360° firing, swarm summon.
- 매 specialized platform + bunker 의 counter 의 essential.

### 매 game design 의 lesson

#### Counter-class system
- 매 explicit damage type.
- 매 50% resistance (not full immunity).
- 매 mixed platoon 의 reward.

#### Anti-steamroll
- 매 single dominant strategy 의 prevent.
- 매 build composition 의 thinking 의 force.

#### Power scaling
- 매 economy constraint 의 add (power cap).
- 매 build choice 의 trade-off.

## 💻 패턴 (응용 — game design)

### Damage type system
```ts
enum DamageType {
  BURST = 'burst',     // 매 high single-shot
  SUSTAIN = 'sustain', // 매 continuous DoT
  AREA = 'area',       // 매 AoE
  FLAT = 'flat',       // 매 generic
}

class Platform {
  resistances: Partial<Record<DamageType, number>> = {};
  
  takeDamage(amount: number, type: DamageType): number {
    const reduction = this.resistances[type] ?? 0;
    return amount * (1 - reduction);
  }
}

const insulated = new Platform();
insulated.resistances = { area: 0.5 };  // 매 -50% AREA
```

### Counter-class matchmaking
```python
def evaluate_attack(attacker_platoon, defender_platforms):
    """매 mixed-damage 의 advantage 의 reward."""
    damage_types_used = set(unit.damage_type for unit in attacker_platoon)
    
    if len(damage_types_used) == 1:
        # 매 monotone — 매 specialized platform 의 fully resist
        damage_type = next(iter(damage_types_used))
        countered = sum(1 for p in defender_platforms 
                       if p.resists(damage_type))
        return 'penalized' if countered > len(defender_platforms) / 2 else 'normal'
    
    return 'normal_or_bonus'  # 매 mixed → 매 some always penetrates
```

### Power budget
```ts
class Base {
  maxPower = 0;
  
  upgrade(structure: 'deep_reactor' | 'fusion_tower') {
    if (structure === 'deep_reactor' && this.deepReactorPower >= 250) {
      throw new Error('Deep Reactor max cap');
    }
    if (structure === 'fusion_tower' && this.fusionTowerPower >= 450) {
      throw new Error('Fusion Tower max cap');
    }
    // ... apply upgrade
  }
  
  totalPower() {
    return this.deepReactorPower + this.fusionTowerPower + this.others;
  }
}
```

### Electronic warfare (Turbulence)
```ts
class NightwatchBunker {
  radius = 300;
  
  applyTurbulence(scene: Scene) {
    const enemies = scene.enemies.filter(e => 
      e.type === 'aircraft' && this.distance(e) < this.radius
    );
    for (const e of enemies) {
      e.movementSpeed *= 0.7;
      e.targetingPenalty = 0.3;  // 매 30% accuracy ↓
    }
  }
}
```

### Build composition optimizer
```python
def optimal_attack_mix(defender, available_units, budget):
    """매 defender 의 resistance profile 의 read → 매 mixed mix."""
    resistance_profile = analyze_defender(defender)
    weak_to = [t for t, r in resistance_profile.items() if r < 0.3]
    
    # 매 weak-against type 의 prioritize
    return knapsack_optimize(
        items=available_units,
        budget=budget,
        bonus_fn=lambda u: 2 if u.damage_type in weak_to else 1,
    )
```

## 🤔 결정 기준 (게임 메타)
| 상황 | 추천 |
|---|---|
| End-game raid | Mixed platoon (3+ damage types) |
| Iridium budget | Specialized platform 우선 |
| Anti-air | Heavy Aerojet + Nightwatch |
| Anti-tank | Metronomos Heavy Turret |
| Counter Warlord Onymite | Mixed bunker garrison |
| Defense layout | 매 50% resistance 의 layered |

**기본값**: 매 mixed platoon + 매 specialized platform + 매 Nightwatch / Metronomos.

## 🤖 LLM 활용
**언제**: 매 War Commander 매 strategy 의 plan. 매 game design 의 counter-class 의 reference. 매 balance patch 의 case study.
**언제 X**: 매 outdated (post-2026 patch). 매 다른 game.

## ❌ 안티패턴 (게임 측)
- **Single damage type 의 attack**: 매 50% resistance 의 wall.
- **No anti-air**: 매 Warlord 의 air swarm 의 wipe.
- **Power 의 over-commit**: 매 cap 의 hit.
- **Defense 의 single layer**: 매 mixed attack 의 break-through.
- **Iridium 의 cheap research**: 매 specialization 의 priority.
