Rather then just test everything out I thought it would be easier to aks it here.
I would love to see all the possibilities of this mechanic.
If the main map (A) has lets say 2 sublevels (B) and (C), then it's possible to travel from A to B and from A to C and back right?
Now here are the questions :

- Do I also need to set A as sublevel of B and C
- Do all (sub)levels and their content stay loaded after travelling (for example: Do corpses stay and does the game remember wich triggers/movers are already have been triggered) --> Like in Quake 2
- Is it also possible to travel from B to C and back while all (sub)levels stay loaded?
- Does it also work in coop?
