Underground

Fortnite Chapter 5 Season 1, titled "Underground," launched on December 3, 2023. Following the multiverse-shattering Big Bang event, players arrived on the brand new "Helios" island. The narrative focused on a conflict between The Society, a shadowy group of billionaires who kidnapped Peely, and The Underground, a rebellion led by Hope and Vengeance Jones striving to rescue him. This season introduced massive overhauls to core Battle Royale gameplay. Epic Games introduced Weapon Mod Benches inside heavily guarded Vaults, allowing players to customize their weapons with sights, extended magazines, underbarrels, and muzzles for the first time. The movement system received a complete visual and mechanical overhaul, adding new fluid animations and the ability to wall-kick and mantle more dynamically. To secure the best loot, players had to defeat five Society Bosses to claim their Medallions. Holding a Medallion slowly regenerated a player's shields but continuously broadcasted their location on the map, creating a high-risk, high-reward dynamic. The island also featured a fully functioning train that continuously circled the map, carrying loot and a hackable chest.
