Rapture Yap

Leave the hub, land in Rapture. Rapture Yap keeps YAPYAP exactly as you know it in the hub, then swaps every dungeon for a Rapture zone built from BioShock's own parts: marble and tile floors, Art Deco walls, pillars, doorway arches, ocean windows, sconces, chandeliers, furniture, Gatherer's Gardens, gene banks, jukeboxes, posters and signs. Three themes (Medical Pavilion, Welcome Center, Fort Frolic) and a new floor plan every run.

What's in a zone

• YAPYAP's own monsters still spawn, as usual.
• Thuggish splicers (Toasty, Lady Smith, Baby Jane, Dr. Grossman) with BioShock's bodies, pipes and wrenches and their real voice lines. Melee only.
• One Big Daddy (Bouncer) per zone. It leaves you alone until you hit it.
• Plasmid wands: Electro Bolt, Incinerate!, Winter Blast, Telekinesis. Cast them like any wand. Found in zones and sold by the shopkeeper.
• The BioShock pistol: pick it up and it replaces your wand attack until you drop it. Six-round clip, ammo boxes around the zone.
• Rapture ambience, score and a jukebox with BioShock's licensed tracks.
• Buy anything from the hub shopkeeper and he welcomes you to the Circus of Values.

Co-op through YAPYAP's own Steam lobbies, up to 6 players. Everyone needs YAPYAP, BioShock and the mod.

Nothing from BioShock is in the download. Before your first Play, Melty runs the mod's extractor against your own BioShock install (UE Viewer and vgmstream, both bundled) and caches what the zones need on your PC.
