"Shown at 50x Speed, this is moving diagonally across the entire Fallout 4 map (From the Upper-Left, behind Vault 111, to the South-East corner, past Spectacle Island) - at the 'jog' pace the character does (not Sprinting, not Walking).

Recently talking about "how long does it take to run across the entire map in Fallout 4", I did a quick Search, but I could not find anybody that just 'ran normally' across the map [that is, the 'jog' that the character does, not Walking or not Sprinting - I read there was a person that did a traverse but was Sprinting all the way across] - so I did one myself, to find out for sure 'how long it takes to go across the map in Fallout 4'...

It apparently takes about 14 minutes and 45 Seconds to 'just jog' across the map in Fallout 4 - from the upper-left corner, to the far South-East corner (each corner saying "You Cannot Go That Way").

[At the end of the video, I check the map a few times, just to make sure that I was 'in the corner', as the 'You can't go farther' message came up when I wasn't quite in the lower corner.

I will Upload the entire Full-Length, Full-Size Video when I get a chance, this was just a quick 'make a GIF to share' thing for a Forum post here at Steam where people were discussing it... it was kind of fun though; other than just finding out 'for sure' how long it takes, I found a few places out in the water (as in, in-the-middle-of-nowhere) that I didn't know even existed lol There are a TON of places in Fallout 4... even if the map isn't the biggest (it is larger than Fallout 3), it has locations packed in like crazy - you can't run a full minute without finding a neat little nook to explore, a place to talk to someone, bump into a random encounter, or a location to go into and take tons of loot out of [to Build up Settlements with!], heh

Have Fun in Fallout 4!"
