The Heatwave is a revamped version of the Scattershot from Halo 4 and Halo 5: Guardians. Projectiles fired from the Heatwave will ricochet around, making it ideal for tight corridors. The Heatwave has two firing modes, horizontal and vertical. Horizontal is suited for general usage and when you’re just hoping to hit a couple of bank shots on random targets. The vertical firing mode is better for hunting down single targets at close range.
