This map contains HDR but you can disable it person by person by doing what the text in the team selection screen says.
You MUST use the navigation mesh included for hostages to work correctly.
This map does take some teamwork to rescue all the hostages.
Best if time round is set to 3:00 minutes, but is ok at 2:45.
There is a triggerable hostage zone to help CT's get the objective done. You must clear the immediate area of all Terrorist and sometimes Counter-terrorists. Just plant and leave the hostage then walk away.
Lots of little things, look for the clues and experiment.
For smaller servers that like to mess around and stuff there is an "admin post" which is an invisible platform on all edges except one. You can only no clip/teleport/fly there.
Keep gravity at the normal level, otherwise you'll miss something great. It will still work, just not as cool.
Please do not rip, decompile or anything else to this level. Thanks.
