multiplayer elements were described as 'passive', meaning that playing with a partner(s) is not mandated, and entirely optional, though certain situations require cooperative play; ai (computer controlled) allies were also to be implemented. the 'passive' multiplayer element included the conversion of a human player companion into an ai controlled non-player character (npc)s if they could be escorted to the home town of the main adventurer; however such ai controlled npcs were not guaranteed to be entirely benign. art style influences were cited as initially including "", "shadow of the colossus", and "the legend of zelda" series. developers also stated they had been influenced by the emergent multiplayer storytelling found in the video game "dayz".
