Homo Sapiens is a Z-machine interactive fiction game written with Inform 6 and is © 2026 by Garry Francis. This game is an English adaptation and port of the Italian 1987 adventure Antropos: Homo Sapiens by Bonaventura Di Bello.
In this game, you play as a prehistoric man in a rainforest: naked, hairy, and afraid. You can't talk, but you can think and you can use tools. Your goals are simple: find food, shelter, and a mate. And survive, of course.
This solution is by David Welbourn, and is based on Release 1 of the game.
SPOILERS AHEAD. Reading a walkthrough prematurely can sometimes diminish one's enjoyment of an interactive fiction game. Please make an honest effort to play the game before reading this walkthrough.
Rainforest (northwest corner)
The rainforest is a three-location maze that is best mapped by listening and smelling in each location to tell them apart. Only the climbable tree that's right here is interesting, but don't forget about the ferns.
The rustling in the tree is a huge snake you should avoid until you're equipped to deal with it. (Except this game is exceptionally kind and never lets you get killed no matter what you try to do.)

Rocky Terrain (near cliff)
There's three locations called "Rocky Terrain".

Edge of Chasm
Don't bother trying to reach the sapling. It's there to act as a landmark.

You'll re-find that shell later. Return to the edge of the rainforest near the stream. There's more geography east from there to explore.

The tree is now on fire. The metal is gone and you won't ever be climbing that tree again. Also, now that the tree is ablaze, the lightning and rain soon stops.

Southern End of Gorge
The storm cleared the crack of its debris, but it's still very narrow. You can only take one thing through at a time, and you also need to be slippery from the fruit. Ferry through the burning branch, the ferns, and the obsidian.

This is the response to ABOUT:
This game is an adaptation of the Italian adventure 'Antropos: Homo Sapiens' by Bonaventura Di Bello. It was originally written using The Quill and Illustrator and published by Edizioni Hobby S.r.l. on the cover tape of 'Viking', no. 10, November 1987 for the ZX Spectrum and Commodore 64.
The data was extracted from the C64 version using UnQuill, translated to English and rewritten for a modern audience with the original author's permission. The new version includes many enhancements that weren't in the original. The coding was done using Inform 6 and the PunyInform library.
Original concept, game design and coding by Bonaventura Di Bello.
English translation, game redesign and coding by Garry Francis.
Play testing by BrownPants, David Etherton, Gianluca Girelli, Joel Burton, Pablo Martinez, Robert Eggleston and Rovarsson.
Surprisingly, I could not find any other ending. You are never killed by the snake, ants, tiger, dinosaur, fire, lightning, drowning, falling, or poison. This game is completely merciful.
