One enemy boss is a canine-like robot, though the player doesn't kill them. Other than that, all enemies are some mixture of human and machine.

While farmed animals are never slaughtered, they are continuously bred and exploited. Also, there is fishing. Farming plants only is possible, but the game wasn't designed around that playstyle.

Zero non-human animals in the game. Can't exactly call it cruelty-free, but there you go, in case you were wondering.

The only enemies are zombies, the only food is apples, the only beverage is coffee.

Pelts are an essential material. Only killing humans is not an option, at least in PvE.

Vegan runs are entirely possible. Sometimes, a mad animal will attack the base and will have to be killed, but that can be disabled before starting a new game.

Any animal interaction is voluntary, and the game's settings allow for disabling of predator animals.

The enemies are all either sentient humanoids or robot-like programs.

Very few enemy animals, who can be avoided. Rescuing animals elsewhere is strongly encouraged. However, some spearfishing is mandatory to advance with one faction.

While there is violence against land-dwelling animals, defeating them "sends them to the Forest of Beginnings", and they can be employed. With money. However, fishing is basically mandatory.
