Three Long Guns manifest as Legendary Bows in Remnant 2, providing your character with powerful weapons with different upgrades and modifications to unlock. Equipped with their own abilities, these bows match well with certain archetypes to dominate tough opponents and bosses. However, each can be tricky to find, locked behind puzzles and rare interactions with entities found within a run.
