High Five

"BOOM! Advanced Rocket Launcher loaded with experimental submunition ammo. Each shot unleashes five Hydra mini-missiles that will lock-on to ground and air targets."

- In-game description

High Five is a specialised variant of the M57 Pilum shoulder-fired heavy weapon used by the United Nations Space Command.

Design details
High Five is an improved M57 that fires experimental submunitions packages containing 9X-G High Explosive, Air Bursting (HEAB) Gyroc rockets more commonly used by the Hydra line of multiple-rocket launchers. The launcher's detachable box magazine still loads two rockets, like the M29 rockets used by standard M57 Pilums, but each contains five 9X-G submunitions within. The fired missiles can lock onto air and ground targets.

Design-wise, it retains thestandard Pilum's launching tube but recolors it to a predominantly white color broken up by olive green and red stripes, along with an olive green falcon emblem in the middle part of the weapon on each side.

Usage
In late 2558, Spartan-IVs serving aboard the trained with the High Five in War Games simulations.

Gameplay
The High Five is an Ultra Rare Power Weapon REQ that grants  REQ Points when sold.

The M57 Pilum is featured as a usable weapon called the Rocket Launcher, in Halo 5: Guardians. It is a power weapon, which fires slow-moving rockets that deal an incredible amount of damage upon detonation, with a wide area of effect. The Rocket Launcher is one of the most powerful weapons in the game, and to compensate, it has a small magazine size, slow reload speed and ammo is generally very rare.
