Hey there, Yes it should be possible to unlock the door, you should be able to connect the Radio Tower to the Gate by dragging a wire from one to the other. If that isn't working, there may be a bug, though someone just played thru and opened the door yesterday, so I'm not exactly sure what that bug is. If you'd like to experience the other ending quickly:
- Go to the old Base.
- Press "Page Down" until you see the Narrative Debug Screen.
- Press F5 to unlock the mouse
- Type 'NarrativeNode_Chapter_6_Beat_2' into the Text Box above the 'Start Narrative Node' button.
- Press the 'Start Narrative Node'
(EDIT) Of Special Note: It looks like there's a bug with connecting the Transformers. If you connect the wire from FROM the Gate Transformer TO the Radio Transformer, it does nothing. If you connect the wire FROM the Radio Transformer TO the Gate Transformer, it works. I don't know why this is happening at the moment but I'll look at fixing it ASAP
