Need to get all buildings to level three for this one and it can't be finished til the end of Chapter 5.
• Bridge
• Generator
• Postbox
• Safe House
• Zip-line
• Timefall Shelter
• Watchtower.
The easiest way to do this is to choose a city that's not far from a lot of other Locations and not far from other cities. (I chose just outside of South Knot City). Build a Watchtower first then upgrade it to level three, this way you can see materials further away.
Then build and upgrade the postbox next door to it. Build a timefall shelter behind these two. Upgrade it to 3.
Those are the best three to start with. If you use the second road fabricator to build nearby, The shelter should generate more likes for you as it's near an timefall hotzone.
Build You Zipline so it links up to Mama's one and upgrade it to two. Then start on your Safehouse (build it next to the postbox) and try to upgrade it to 2 (or as close to two as you can get it).
If you need materials, raid every NPC safehouse and City as you do standard deliveries. At this point both the Safehouse and Zipline are level two. Focus on the safehouse as it requires more materials. Once that is level three. Chose a location nearby and build a bridge (somewhere people are likely to use it), if you don't mind a trio, north of the Photographer is a set of deep rivers. You can build and upgrade one there last of all to generate easy likes.
Upgrade the zip-line to 3 and now finish the bridges uogrades as the materials are really easy to find out in the wilds and inside cities and safehouses.
Focus on your own buildings as I helped upgrade another players bridge to level 3 and it didn't unlock until I'd done my own one. Just to be safe, focus on your own.
