Save entire GameState while change Room (Like Resident Evil 1)

Hi there,

i have a Problem to find out, how can i save all the variables and actors and the stuff while changing a Level (or a room) like in Resident Evil 1.

I know i can make a Savegame with the Create Save Game Node, but i cant make a savegame everytime the Player Change a room. Is there a way, that variables and all the states are not killed by the Program? (I mean save all: Positions of actors, light are on or off, doors are open or closed, enemys are dead or not…)

Or is there a easier way to save all that stuff?

Greetings
Beregron

EDIT:
Conitect have made a save function on their Engine, that saves the complete game (all variables and so on). Is something planed on Unreal Engine?
