A second suicide vessel alongside the chaser, but where the chaser simply beelines, this one is a rhythm the player can read. It drifts in from beyond lock_range at half speed, LOCKS a point, rocks 30px back and forth along the charge axis for 1.2s, draws a thin line down its trajectory for the last 300ms, and only then crosses the gap in one straight 950px/s run before coasting to a stop and starting over. The lock is what makes the wind-up worth anything: nothing re-reads the fleet once it begins, so the charge goes where the target WAS and stepping off the line works. Same bargain as EnemyBigLaserBeam. EnemyLungeComponent is a Node2D rather than a plain Node because the trajectory line has to be drawn somewhere, and top_level keeps that drawing in world space while the hull it hangs off spins to face the lock. The roaming spawner gets a 25% lancer share. It is the only place the player meets an enemy off an authored map, so without that the lancer would exist only in the setup editor.
