Casualties: Unknown Layers and Character Unlocks

How many layers are there

The official store lists 11 layers on the foreign planet where you are sent to retrieve lost cargo. The layer guide gives the same total. Sources: Steam, layer guide and ending guide.

What 1.0 added

The demo covers layers 1–5, while the full game adds layers 6–11. The community update log also records those six deeper layers shipping with 1.0. An older five-layer walkthrough therefore stops at the demo boundary rather than describing the complete game. See the demo boundary and release history.

Can I reach the full ending in the demo?

The documented demo stops at layer 5; layers 6–11 belong to the full game. Use the full release when following full-game progression references. The supplied sources do not establish an alternative demo route to a full-game ending. See the layer availability table.

Named environments

The layer index identifies Gravel lands as layer 1. Start with the beginner guide for initial controls and preparation instead of treating this reference as a floor-by-floor walkthrough. The named starting environment is documented in the layer index.

Endings

The ending guide records three endings announced for the full game, and the update log records three endings in release 1.0. Neither source establishes a complete, independently tested branching walkthrough. Do not infer exact item requirements or route choices from the ending count alone. Sources: ending evidence and release history.

What setting prevents finishing the game?

Endless does. Its release description says layers loop after a certain point, continuing until death, and explicitly says the game cannot be beaten that way. If an ending is your goal, check that setting before starting the expedition. See the developer's release settings text.

Characters and unlock order

The three characters are Experiment (SAW-01), Milky (SAW-03) and Dune (SAW-12). The developer release text gives their identities, while the character guide separately lists their names and codes.

The release unlock message says to finish a run with the previous character. The character guide interprets the progression as Experiment → Milky → Dune. It does not independently verify every qualifying outcome. A death or arbitrary ending should therefore not automatically be treated as a confirmed unlock trigger. The store describes distinct playstyles, but detailed trait values and build recommendations are outside this verified reference.

Planning a run

Before choosing an ending attempt, confirm that you are playing the full game and that Endless is off. Then use the beginner guide for preparation and saving guide when planning breaks. Those linked pages handle their own controls and version notes rather than duplicating a walkthrough here.

Evidence limits

The eleven-layer total, full-game layer boundary, character count and Endless restriction are documented. Exact ending routes, branching prerequisites and qualifying character-unlock outcomes remain unverified; no successful ending run is claimed.
