So I’ve been seeing a lot about the zone unchained mod and it seems really great, but I was curious about something before I try it out. How much is actually available with the story basically being turned off? What I mean by that is, there are a lot of locations locked due to completing and progressing through the story/missions, like underground labs and certain other areas I’m sure you all know what I mean. The super cool big open rooms and other under ground locations and stuff. I’m assuming those locations wouldn’t be accessible with out story mode or certain missions. Anyone have any ideas?
