: My answer is: None. They're all exits. I mean, does anyone _want_ to go in
: there? And once you're there, do you want to hang around?
Normally, you'll only have to enter The Labyrinth three times:
- Once from 'Beware of Low-Flying Nightmares'. This should be our first time in The Labyrinth, if we're playing the game in the right order.
- Once from 'Need A Light?'. This is when we have to come back up after killing the Big Blue Meanie and grabbing the M-79 Grenade Launcher.
- Finally, once from 'Lasciate Ogne Speranza, Voi Ch'Intrate'. This is after we've killed the Demon, grabbed the Gemstone, and set the bomb.
So, really, there are three ways we'll actually be entering The Labyrinth, and three ways we'll be leaving it. This assumes, of course, you've read the walkthroughs and decided to take the other path from Ground Floor instead of heading into The Labyrinth from Happy Happy, Carnage Carnage.
