🛑 WARNING: BACK UP YOUR SAVE BEFORE YOU USE THIS MOD! 🛑

⚠️ This is an ALPHA and it CAN DESTROY YOUR SAVE. Air Defense is brand new and has only been played in a few test games. A bug can break or corrupt your save game, and the mod cannot be removed from a save again once added. Make a copy of your save before you add it, and keep saving to NEW save slots while you play with it. On top of that the raids destroy buildings on purpose, so don't switch them on in a game you can't afford to lose.

💬 If you run into any problems while testing, just let me know in the Forum tab of this page - and the same goes for suggestions and wishes: which systems, threats or features you would like to see next. Every report helps!

🛡️ Air Defense

Your factory has grown big enough to be a target. Build up an air defence in four tiers and fight off waves of Russian attack drones and missiles - an endgame challenge you switch on when you are ready.

From the first buzzing Geran-2 swarms to Kinzhal hypersonic missiles: the raids grow with every wave and come in from up to three directions. Whatever gets through destroys the building it hits. Stop them with 11 NATO air defence systems, your own munitions factory and missile plant, and watch every raid live on the radar screen.

Features

• 🎚️ Only when you want it: raids stay off until you switch them on in the Defence window (Shift+F8). Easy / normal / hard: a wave every 30 / 20 / 12 minutes, stronger each time.
• 🛩️ 13 Russian threats: Geran-2 drone swarms, Geran-3 jet drones, Kalibr and Kh-101 cruise missiles (fly in low, pop up and dive), Iskander-M and Kinzhal ballistic missiles falling almost straight down - and since 0.3.0: Lancet loitering munitions that hunt your air defence, Orlan-10 recon drones (every one that gets away makes the next wave stronger), Gerbera decoys that eat your ammunition, KAB glide bombs, the P-800 Oniks sea-skimmer, Kh-31P anti-radiation missiles that go for your radars and the hypersonic 3M22 Zircon. Every 10th wave is a massive combined strike.
• 💥 Real damage: a hit destroys the building (no refund, just rubble), cruise and ballistic missiles also take out what stands next to it. They go for your air defence first, then power plants, solar panels, the captain's office, factories and vehicle depots - and a hit on the shipyard burns part of its cargo.
• 📡 TRML-4D early warning radar: sees raids as soon as they set off (the siren goes long before they arrive) and makes every gun 25% more accurate.
• 🔫 Bofors 40 mm, Gepard 1A2, Phalanx CIWS: from the cheap first gun to the drone-killing AA tank and the 75 rounds a second last line of defence. Turrets really turn, guns really aim and fire tracers; shells that miss fly on and burst in black puffs.
• 🚀 Patriot battery: AN/MPQ-65 radar and M903 launchers with 16 PAC-3 in four 4-packs, one launch every 3 seconds. When they are spent a missile transporter backs up and its crane swaps in fresh canisters. The only real answer to ballistic missiles: two interceptors per Iskander or Kinzhal - and even then one sometimes gets through. It keeps missiles back for them and leaves drones to the guns, with a minimum range like the real thing; a Missiles only switch keeps a launcher for missiles alone. Now and then a PAC-3 fails and tumbles out of the sky - very rarely onto one of your own buildings.
• ⚡ DragonFire laser: burns drones and cruise missiles out of the sky in seconds, no ammunition, just a lot of power.
• 🎯 Skyranger 30 with AHEAD airburst rounds and the Avenger with Stinger missiles: the short-range drone killers.
• 🛡️ IRIS-T SLM and NASAMS (with its Sentinel radar): medium-range missiles against drones, cruise missiles and glide bombs.
• 🌌 THAAD with the giant AN/TPY-2 radar: catches ballistic missiles high above the island.
• 📶 ARDRONIS jammer: drones lose their navigation and drift off course, or lose their link and spiral down. Inflatable Patriot decoys draw the enemy's fire.
• 🚀 HIMARS strikes back: after every wave it fires ATACMS at the enemy's launch sites - the next wave is smaller.
• 🏭 Your own ammunition: a munitions factory makes explosives and 40 / 35 / 30 / 20 mm rounds, a missile plant builds the PAC-3, Stinger, IRIS-T, AMRAAM, THAAD and ATACMS missiles. Everything goes to the sites by belt.
• 🗺️ Radar screen: a live map of your island with your defences, radar coverage and sweep, every tracked drone and missile with its trail, interceptors in flight and who is shooting at what.
• 🎥 Click and follow: click any drone or missile in the world (like a vehicle) to see its speed, height, target and time to impact, and let the camera follow it all the way down.
• 🔊 Sound and effects: air raid siren, buzzing engines, gunfire, launches, violent explosions as big as their warhead with fragments, black smoke and burning craters.
• 🏅 Unity rewards: everything you shoot down earns Unity at the end of the wave.

How to start

1. Research Air defense (after Ship weapons and Ship bridge II): the early warning radar, the Bofors gun and the munitions factory, in the new Air Defense tab of the build menu.
2. Build a munitions factory (ammonia + acid → explosives; steel, copper and explosives → shells) and feed your guns by belt. Every site also needs electricity, workers and maintenance.
3. Go on with Air defense II (Gepard, Phalanx), Air defense III: Patriot and Air defense IV: DragonFire - and since 0.3.0 Short-range air defense (Skyranger 30, Avenger; after Air defense II), Electronic warfare and deception (jammer, decoys), Medium-range air defense (IRIS-T, NASAMS), Deep strike: HIMARS and Air defense V: THAAD.
4. Open the Defence window (top bar or Shift+F8), pick a difficulty and switch raids on. The first wave comes 5 minutes later; Next wave now starts it at once.

Good to know

• Can be added to an existing game; raids stay off until you switch them on. It cannot be removed from a save again. A game saved with 0.3.0 cannot go back to 0.2.x.
• The Defence window shows the next wave, the wave underway, all your sites and the history. Each site's window shows its target, ammunition and kills; the radars' windows have their own radar screen.
• Dev mode under the radar screen shows every drone and missile, also those nobody sees yet, with their flight paths and targets.
• English only for now. Made for Captain of Industry 0.8.8.
