From the other thread:
Singleplayer FoV used in Multiplayer, but only if you are playing alone.
Oh, and level suggestions for MP. Since I don't know the full list of full-version MP levels, I'll post a list here.)
Levels with a ? mark are because it would take time to replace items with GemItems in it, or the level is more of a linear level in design, or the level could be considered difficult by the average player). I don't expect most of these to make it
