The penultimate mission in the Chicken Invaders Universe, the Ironman Competition will test your shoot em up skills up to the breaking point. First comes an overview of the mission.
50 waves
The normal waves are Chicken Invasions, and the boss waves are Double Teams.
100%-100% difficulty (+40% from being locked to Superstar Hero)
+80% projectile speed (+30% more from Superstar Hero)
3 environmental hazards: Massive, Lightning, and either Hot or Frozen
The best way to prepare for Ironman is to play many practice runs. Barring that, flying Elite Chicken Invasion and Double Team missions is the next best practice. Once you are ready to compete, its time to assemble your load out.
Spacecraft
VF-66 Jackdaw - This is the easiest spacecraft to pilot courtesy of its small hitbox and environmental immunities, but is not recommended for a high score run. Its firepower caps out at 9, making it harder to attain points from multi kills, clean sweeps, and so on. If you are only concerned with beating Ironman, choose it.
M400/M404/M408 - These offer a nice middle ground in terms of maneuverability and firepower. They don’t require as many maneuvering jets as bombers, yet have ample firepower to ensure a high score.
BX-9 Mjolnir - The preferred vessel for high score runs. The BX-9 possessed unparalleled firepower thanks to its twin pylons. Its downsides are its large hitbox and the need to equip more maneuvering jets to move quickly. Furthermore, it is not recommended for less skilled players since they will die too often to maintain the BX-9’s firepower advantage.
Booster
There is no consensus on which booster is better. My experience is that if you have coolant canisters, overdrive is better. If not, accumulator is better.
Weapon
To maximize your score, pick up every present that appears. If your only concern is winning, then the positron stream is the best weapon. Absolver doesn’t do enough damage in DTs and is terrible against specific waves (Spiral of Doom, High Speed Chase).
Special Weapons
Missiles/Mines - You want to put these in 1 or 2 slots to clear hard waves such as Palpitating Grid. They deal high damage to everything on screen and destroy enemy projectiles. Keep in mind that using a missile or mine may forsake bonus rewards, resulting in lower score.
Damage amplifier - Great against bosses and hyper dense clumps. Use this to dispatch Double Teams as they are the hardest waves in the mission.
Dimensional phase out - Basically an invulnerability potion. Use when getting hit is unavoidable or if you need to put yourself in a risky position to deal damage.
Other mountables
You will need maneuvering jets if you are flying a muller or especially bomber. Eggular repulsers are useful for reducing the latter’s hit box. Lastly, Appetite Attractors are a must have for high score runs, to tractor in food. I’ll let you work out which of the remaining mountable are useful.
Satellites
Barbequer - A staple for bombers, the Barbequer does high damage to anything caught in its flames and destroys enemy projectiles. Get close and personal to a boss and unleash the fires of teriyaki chicken BBQ.
ICBM - A thrifter’s missile, it does considerably less damage, is slow, and must impact something to go off. However, each satellite holds 5 ICBMs and you have up to 5 satellite slots depending on your ship. Best used against swarms.
Bird Flu Gun - Compared to the ICBM, it has more ammo and a faster fire rate. However, it does less damage per blast and does not destroy enemy projectiles. Still useful for crowd control, but not a good option all around.
Microgun - The minigun is practically useless. It has no utility unlike the other satellites and while it does more single target DPS than ICBM and bird flu, it suffers from lack of AOE and a narrow cone of damage.
Once your setup is configured, it is time to fly the mission. Generally you want to be on the alert, have good reaction time, and avoid getting backed into a corner. When dodging, small controlled movements are better than drastic movements. Know which waves to use special weapons on so you don’t find yourself depleted when you stumble upon a hard wave.
Double Teams are the hardest types of waves in the game, and the increased projectile speed and environmental hazards in Ironman add another level of difficulty. The easiest way to beat them is to use Damage amplifier and burst down one boss. If that’s too risky, activate Dimensional Phase out simultaneously. Common sense says to destroy the more dangerous boss of the 2. Opinions differ here, but the general consensus is that Crabs and Mysterious Ship are among the harder bosses and Mother Hen Ship, Iron Chef, and Big Chicken are the easier bosses. Experience is the best way to tell.
That’s all I have for now. If anyone has additional tips, feel free to chime in.
