Complete mission on touching exit door?

[SirArthurIV]

I am trying to make a mission that is similar to Shauna Stockwell's Shut Down the Superdyne Den where you go through an empty warehouse and have to defeat an ambush on the way out after touching a glowie in the back end and you don't get a "mission complete" until you exit out the front door.

You can set the mish to where the player must exit through the original entrance, rather than click to leave.

As an alternative, you can use the Police Station map. There's a weird bug with that map which causes the mission to not complete until the player has taken the elevator to the jail section.
