Assassin's Creed: Black Flag is the second largest work in the Assassin's Creed series. This is because the map is set in the Caribbean Sea, and most of the maps are composed of waters. It takes a long time to just use a boat to cross the entire map, so what if it is swimming?
How Big is the Map tried this feat - Edward traveled through the entire Assassin's Creed 4 map through swimming, that is, swimming through the Caribbean Sea only took 4 hours, 51 minutes and 15 seconds. The entire process of traveling through the map was only occasionally encountered some naval battles, more of which were the calm Caribbean Sea, and a good aerobic exercise for Edward.
This channel has also conducted cross-border map tests on other games before, such as walking through the map of Assassin's Creed Odyssey in 3 hours and 58 minutes, and walking through the Kalimdo continent in World of Warcraft.
