Helix is a weapon in Black Paradox.
Firing this weapon creates two stacked streams of four projectiles each which travel in a narrow crisscrossing sine wave pattern across the screen. Damage for this weapon is maximized when both streams of projectiles come into contact with an enemy, and so the distance and position of the player is important and may require constant adjustment to ensure as many projectiles as possible meet their target.
This weapon does not slow player movement while the Fire button is held.
