I just want Freedom Survivor with Helena's office (DOA5 story), The Deck, The Ballroom, The Stockroom (DOAD) and The Aquarium at the center (DOA3).
Danger zones would be related to the fact that the ship is sinking/being attacked by MIST/exploding after a "certain incident", in order word, going Titanic.
Each stage of the ship would give fighters "sloppy situations" (the ship is randomly leaning left/right in Titanic Mode, you can turn it off in options).
Helena's office : you can throw the opponent through the window, leading to The Deck : desk is an obstacle, sofa too, and there is also a mini-bar with glass destruction. Nice attention to details
Titanic mode >>> there are a lot of furnitures destruction, and if the floor breaks, the characters go down to The Ballroom
The Deck : you can either throw your opponent to the front of the ship (The Ballroom), center of the ship (The Aquarium), or to the back (The Stockroom) ; there is a nice and calm sunset and seagulls flying around
Titanic mode >>> there is a firework in the background, and things are exploding around. Just a slope.
The Ballroom : there are buffets and other dining tables to use as obstacles, and there is a concert in the background (opera/jazz/rock options), full of fancy people, wines and nice food
Titanic mode >>> no NPCs anymore, the room is burning and the floor is wet ; you can throw your opponent to a giant candelabrum
The Stockroom : a lot of explosives like in DOAD, but you can also go to a covered warehouse/machineroom full of mechanical stuff ; this is actually where the "incident" happens in Story Mode
Titanic mode >>> giant explosions ; the machineroom part is destroyed/flooded and not available
The Aquarium : plenty of colorful fish and good lighting effects, you can break the glass a bit which makes the room slippery ; mermaid Kasumi can be spotted swimming in the background sometimes
Titanic mode >>> the fish tank's glass is entirely broken, fighters have water up to their calves and fish are choregraphically jumping out of the surface
Think APOCALYPSE, with real dead or alive situations for your character.
