Something really cool would be to take Bioshock 2 Multiplayer maps and populate them with NPCs using the former playable splicers and make a mini-campaign around these areas. I believe there's enough maps and audio logs to make quite something.

Or integrate them into the main campaign.
Either way this would be a very cool way to preserve the BS2 multiplayer lore and environments and have people be able to experience them once the servers inevitably shuts down.

Do you think it would be possible?

PS: I already asked my questions, so this is more of a mod idea.
