Assassin's Creed Shadows originally didn't have yellow paint, but players were struggling to find their path without it.The game's creative director, Jonathan Dumont, explained that playtesters were having difficulty in navigating the hidden trails activity.The lush and full environment of the game required some guidance, hence the addition of yellow paint as a visual aid.The yellow paint helps players to see the intended path in the parkour exams and makes navigation easier in Sengoku-era Japan.
