Confirmed: It's more open than Tetris.
When asked to detail the range of the open world in Firewatch from a scale of 1 to 10, a developer for Campo Santo responded by saying "5."
"If Tetris is a 1 and Skyrim is a 10, I would say Firewatch is maybe a 5," ThatJaneNg of Campo Santo responded. "I would kind of describe the world of Firewatch like how a ski resort is laid out. There are multiple ski trails / bowls on a mountain. Some areas have defined trails but some areas are more free-form, and they are all linked."
Considering Firewatch is 100 percent story and character driven, that open world estimate of "5" didn't come as a surprise...
