Identity and unlock

Experiment, often called Expie, is the default playable species and carries the designation SAW-01. The community character comparison lists starting STR 9, RES 8 and INT 7, making it the baseline against which the other two bodies are described. You do not need to finish a previous character to select it. Completing a run as Experiment unlocks Milky according to that same comparison; unlocking Dune comes later in the chain.

What changes your first run

Experiment can read notes and E-PDAs, hug survivors and haggle. It is also the only playable character listed as able to take the training courses. That combination makes it a useful starting point for learning both physical interactions and the information found in the world. Its Canine quirk flags theobromine intolerance, so a familiar-looking snack is not automatically appropriate food. Its bioluminescent sight supplies a small emergency light around the body, which helps orientation without replacing a working lamp.

Height, appearance and lifespan

The species article describes black fur, an orange-tipped tail, orange eyes and three soft horns behind the head. Its stated height range is 130–160 cm; that is a range rather than a fixed height for every generated character. The playable comparison gives a standing collision height of 5.2 tiles, which is a separate gameplay measurement. Neither the species description nor its comparison supplies a confirmed natural lifespan. Starting ages are not a lifespan estimate, and this page leaves that question without an invented number.

Lore and gameplay are different records

The community species article connects SAW-01 to the corporation’s artificial-species research, but it also warns that visible gameplay abilities do not always establish lore facts. A jump measurement, a sprite glow and a scientific description should therefore be read in their own contexts. The spelling expire sometimes appears in searches; Expie and Experiment are the names used for this character.
