Game Breaking Bug
If you’re like me and got bugged after the second drill, do not go back towards the first drill.
I missed the first data pad (I slipped and fell) and when I walked into the room with the first drill, it triggered it as an objective again. When I went to hit the elevator, having no idea it was supposed to go down until watching a video on YouTube, it went up to the exit and triggered the same intro sequence with Keenan and the villain, and dropped me back down with no way to proceed. Having no backup saves (moron) I thought I had trashed everything in the DLC.
Don’t be me. Don’t go back for the data pad. If you do, I hope this helps.
