Please be advised - further information reveals preppers names and locations.

I would like to thank Mr. Bird and Mr. Vampair, and all fellow porters for their time, guides, videos, screenshots and online structures which helped me very much on my Sam's way.

I sincerely hope that we can help new players with ziplines more efficiently if we'll use universal "main route" positioning. To that purpose, I humbly present my own work, building up on Mr. Bird's wondrous guide - coordinates for "main route" right on the map.

Also, I'm sharing my take on zipline locations' screenshots, with coordinates in plaintext for each screenshot.

I've added coordinates to each "main route" tower marked on the map.
You'll need to zoom in to see the numbers.

Coordinates format is "XXX - YYY". If XXX and/or YYY are negative, it'll look like "-XXX - -YYY".

Thanks for reading this guide.
Again, please check out Mr. Bird's and Mr. Vampair's guides, too - and maybe leave a Like for those who came before us? ;)

At this point of time I've finished DS1 on "Very Easy" mode to cherish the story.
I think that if I try to go for LoLoLs in the future on the "Very Hard", I'll expand this guide with Eastern zipline network, too.

Keep on keeping on, fellow readers. Never give up. Never surrender. A day at a time.
