So I started up a normal and decided to do a simple playthrough to see how far I could get. I encountered two bugs.

1. Major texture bug: I was in the tesla gate hallway where a Foundation employee runs through the tesla gate. After she died, I went through it like normal. Upon hitting the button to open the door on the opposite end of the hallway, the walls and everything around me went black. I couldn't see anything. When I died by running into a tesla gate, everything went back to normal. It didn't happen second time I opened the door.

2. I went to the small Test Room and picked up an S-NAV. Immediately upon using it, the game froze. I exited out and got an MAV.
