The full game released on 9 November 2026. It is a different Steam entry from the free demo, and release 1.0 adds layers 6–11, endings, two additional playable characters and extensive changes.

The full-game store describes 11 layers and 3 characters. The launch announcement also names 40 achievements. These are release features, not proof that the demo received the same update.
More than extra levels
Release 1.0 adds prosthetics, Endless mode, item colors and labels, health-panel information and many fixes. It also changes recipes and some item behavior. A demo-era screenshot can therefore be wrong even for an apparently familiar mechanic.
Mods and languages
Select the package’s exact target. Casualties Together v5.5.0 targets full game 1.0; older release notes include demo 7.0.1 targets. The locale repository also separates release and demo JSON files.
What to do first
Use the official Steam entry to install the edition you intend to play, then inspect its current version before applying third-party changes. Follow download and requirements for the official route, or multiplayer compatibility before joining friends.
