Scourge Fighter

Scourge Fighter is a Hardmode boss that can be fought anywhere at night. Although encountering him is optional, the weapons he drop can be useful to obtain.

Spawn
Scourge Fighter can be summoned anywhere with a Scourge Remote during the night.

Behaviour
Scourge Fighter cycles between three attack phases while summoning minions, with a fourth attack that can be used during any one of these phases. If the player greatly distances themselves from Scourge Fighter, the boss flies towards the player and does not attack until it is within a certain distance of the player (~120 Blocks).
 * However, the Missile Strikes will still be in effect regardless of distance between the boss and player.

Attacks

 * Scourge Fighter repeats the following attack pattern:
 * Chases the player while firing bursts of bullets.
 * Flies horizontally above the player, leaving a trail of napalm that bounces on tiles before disappearing.
 * Releases short-living homing missiles.
 * Every 20 seconds, a missile strike is initiated, which rains down three waves of missiles from the sky.
 * During the battle, Mini Fighters will be summoned which shoot lasers at the player.

Tips

 * Building a long platform bridge stretching a long distance as an arena would make the boss fight easier.
 * Great Mobility is vital to being able to handle this boss and dodge most of its attacks.
 * Prioritize dodging the missile strikes when they occur as they can deal massive damage and are hard to avoid.
 * Building a row of solid blocks above an arena will protect against the missile strikes, as they explode upon hitting a tile.

Trivia

 * The theme playing during the fight with the Scourge Fighter is called "Binary Overload" and has been composed by Ranipla and GENIH WAT.
 * The old theme was called "Mechanical Imbalance" and was composed by Ranipla.

Quotes

Lore
A mechanic, captive in the Dungeon had created the three mechanical instruments of destruction, commonly referred to as The Destroyer, Skeletron Prime and The Twins, and recently, word has spread. A team of martian scientists, after hearing of the destruction caused by those machines, felt a surge of inspiration and tried to replicate and upgrade such a machine, so it could help them in invading the Terrarian lands.

Unlike those mechanical.. 'creatures,' if you could call even call them that, the scientists had treated their project as a top secret super-weapon, dubbed the '064A-SCOURGE" - a machine to lay waste with its insane speed and along with that, quantum warp abilities. Its AI was intentionally made advanced, so to be able to track down enemies easily and leak their locations.

The tests were a success, and it was developed even further, to surpass its current limits. It all resulted in the 064A-SCOURGE, now referred to as the Scourge Fighter, to have been a near perfect machine, with an equally immense strength to match. It was given a base command to 'destroy any threat,' but before any more commands were added, the machine was tested in a building. But the amount of power it exerted, caused enough damage to tear a hole into a nearby wall, big enough for it to escape.

At first the martians thought to capture it, but then quickly decided otherwise, and instead, simply follow what the Scourge Fighter does with only a singular command, and hoped that this one command would be but enough, for them to take over the Terrarian lands.
