Please consider adding more light to places like this.

As a rule of thumb: People will find your map to be about 2 or 3 times as dark as you do!

So if you already start with a pitch-black room, you're probably making a mistake!

I know that you want to force people to used the flashlight and such (very well done in Episode 1!) but never forget, this is a multiplayer map. It means people play it at different times and cannot really control when a server changes to it.

As a result people will be forced to play the map a daylight. Reflections in the monitor, badly configured too dark screens, ect, ect. People will leave the server and have bad memory of your map if they can't see anything for any reason at all.

Add some torches! You can leave two or three dark corners but you won't regret lighting the place up a bit. I bet.
