There is almost nothing like Once Human, largely because it is not like any one thing. Instead, Once Human tries its best to be a little bit of everything thrown into one big pot, as it technically falls under multiple genres and borrows many of the elements that make those genres unique. As a free-to-play, multiplayer, open-world, third-person shooter, post-apocalyptic survival horror game, Once Human has clearly been inspired by plenty of other titles, with games like Tom Clancy's The Division and Fallout 76 being some of the most obvious influences.
