I don't want to be that guy.
But I thought the idea of being stranded adrift on a large CRUISE ship in the middle of the ocean was a great idea.
Very atmospheric and rickerty, and it was crucial to the story which is why the whole campaign (mostly) was set out on the ship.
Resident evil 6 had 1 chapter, on a sub. (Ada)
2 chapters on a carrier boat (Chris / Ada)
And 2 chapters in a weird underground base which happens to be underwater (jake / Chris)
If "revelations 2" did exist I very much doubt they would base it on a ship again, but I hope wherever the setting was is just as atmospheric.
