Per-Round Drain (3 rounds total)

Resource	Per round	Total over 3 rounds

Side Effects

Counts as aggressive action: propaganda vs target −15% permanently
If target's population reaches 0 from drain → country defeated

☢️ Nuclear Strike

Always succeeds. Never recovers. Earth bleeds.

Requirements

Uranium enrichment 100% OR nukes_ready ≥ 1
At least 1 nuke in inventory

Cost (always paid)

−25% of own money
−5% of own population (refugees flee)
−1 nuke (consumed)
Enrichment → 0% (full reset)

Damage to Target (always succeeds)

−65% of target population + 8M flat (e.g. 100M pop → ~73M dead)
−30 military
−50 money (flat)
☢️ Radiation: 3 turns — each turn target loses:
- 8% of current population + 2M flat
- 10% of money
- Population growth halted (no +0.5%/turn during radiation)
If target population ≤ 0 OR < 5% of original: guaranteed elimination + ⭐ Victory Star

Diplomatic Fallout

Existing relation with country	Penalty applied

Neutral (−20 to +20)	−30

+3 influence (capped 100)
+$5M sent to chosen target country (military aid)

🛡️ Build AA Defense

Three tiers of escalating bomber-killing power.

Tier Costs & Effects

Tier	Base Cost	Population Multiplier	Bonus vs Air Strike	Enemy success rate
1 — Basic AA	$500M	clamp(0.8 + pop/500, 0.8, 3.0)	+15% defense	55%
2 — Advanced AA	$1,000M		+25% defense	45%
3 — Elite AA Network	$1,500M		+35% defense	35%

Must buy tiers sequentially (1 → 2 → 3). Final cost = base × population multiplier.

🛰️ Install Radar

One-time purchase, every-turn intel — until someone bombs it.

Cost & Requirements

Money (flat — no scaling)

$800M

Action slot

1 of 3

Player only

Yes — AI cannot use this action

Limit

1 radar per country (one-time)

AI countries can also own radar but acquire it via a separate auto-purchase: each AI turn, 15% chance to spend $800M if they don't already own one.

What It Does — Auto Intel Report

📡 At the start of every turn, an automatic intel report is added to your news feed
Reveals current military units and cash reserves for 2–3 randomly selected AI countries (eligible = AI + population > 0)
Sample format: 📡 AUTO INTEL: Russia: 47 military, $312M | China: 62 military, $890M
Persists every turn until destroyed — no upkeep cost

Vulnerability — Destruction Risk

⚠️ Each successful enemy air strike on you rolls a 15% chance to destroy the radar
Failed (intercepted) air strikes do not threaten the radar
Once destroyed, you must repurchase ($800M again) to restore intel
Attacker who destroys it gets a bonus message: "🛰️💥 BONUS: Enemy radar dish DESTROYED!" (no resource bonus, just bragging rights)

Strategy Notes

Pairs perfectly with Tier 2/3 AA Defense — fewer successful air strikes = lower destruction roll frequency
High value early-game: $800M is steep, but getting 2–3 free intel reports per turn for the rest of the game outclasses any single-action info gathering
Reveals only military & money — does NOT reveal nukes, enrichment %, AA tier, or population

⚛️ Buy Uranium Enrichment

Speed-run to 100% (= 1 nuke).

Tier Pricing

Enrichment Gained	Base Cost
+5%	$100M
+10%	$250M
+15%	$500M
+25%	$1,000M

All costs scale via the same population multiplier as AA: clamp(0.8 + pop/500, 0.8, 3.0)

🔁 Per-Turn Passive Mechanics

What every country gets just for surviving each turn.

Income Per Turn (scales with population)

Resource	Formula	Example (300M pop)
💰 Money	pop × $2M	+$600M
🪖 Military	max(1, pop/10) + 2 regen	+32
📊 Influence	max(1, pop/50)	+6
👥 Population growth	pop × 0.5%	+1.5M
⚛️ Uranium enrichment	+7% / turn (until 100%)	+7%

☢️ Population growth is HALTED while a country is suffering radiation poisoning.

Country Elimination Triggers

Population < 0.5M (500K) → automatic defeat by collapse
Air strike when population < 5% of original → 20% chance leader assassinated → eliminated
Nuclear strike that drops population ≤ 0 OR < 5% of original → guaranteed elimination
Eliminator earns ⭐ Victory Star

AI Strategic Purchases (each AI turn)

25% chance to upgrade AA defense if affordable
15% chance to install radar ($800M) if not already owned
