Hades boons splice into plasmids as you clear Rapture, room by room.
Launch BioShock Remastered through Melty with Hades installed and Rapture Run opens as a solo roguelike overlay. Clear the first Splicer room, choose one Hades-sourced Olympian plasmid, then carry that build into the next room.
The two original 2D combat arenas are inspired by Medical Pavilion and Neptune's Bounty. The mod reads BioShock's installed emblem and map package metadata, and reads Hades' installed trait data; it does not redistribute game assets or replace BioShock levels. The overlay closes with F10 or Ctrl+Escape.
Controls: WASD or arrows to move, mouse to aim, left click or Space to fire, Shift to dash, 1/2/3 to choose a plasmid.
The mod installs an x86 DXGI proxy to load its in-process BioShock plugin. That filename can conflict with another DXGI proxy, such as ReShade or another mod loader.
