Feel free to post any strange things you've found in the game that may or may not be useful to a speedrun.

¤ If you use Ellie Satler's id to enter the Raptor Pen from the Visitor Center, the game will check to see if you have the Visitor Center night vision when entering Raptor Pen dark rooms. This is because the game only checks to see if you have a dungeon's night vision when you first enter a building and never in the middle. I'm not sure what would happen if you have the Raptor Pen night vision then try to get the Visitor Center night vision, would be interesting to see.
