Legion Breaker demo vs full game
The full game launched on 13 October 2026. Much of the advice indexed before that date describes the demo or the itch prototype. Here are the differences we can actually trace to developer statements.
Full game and demo at a glance
| Question | Full Steam game — 4425980 | Demo / older evidence |
|---|---|---|
| Campaign size | Release announcement: 12 unique battlefields, each with a boss. Legion Breaker is Out Now! | Dev Log #1 says the demo has the first three levels. It also previewed 15 for the future full game; that projected total was superseded at launch. Giants, Direwolves, Lightning, and More — Dev Log #1 |
| Ending | The release announcement says the Necromancer King eventually faces you. Legion Breaker is Out Now! | v0.6.0 says beating the demo’s final boss ends the demo instead of replaying the last map. This does not identify that boss as the full game’s final boss. v0.6.0 — Balance Changes and CJK Language Support |
| Archers | HISTORICAL EVIDENCE Later full-game development logs describe elemental archers and spearmen. Exact current unlocks are not independently played. Guardians, Thunderstorms, and Ash Colossi — Dev Log #2 | v0.6.0 explicitly moves archers to a later level so they are no longer in the demo. v0.6.0 — Balance Changes and CJK Language Support |
| Inner Fire II | HISTORICAL EVIDENCE Described as an extra HP upgrade originating in the full game. Exact v1.0 cost not given in that note. | v0.6.1 includes Inner Fire II “from the full game” in the pre-release version. Shared upgrade names do not prove the versions have identical trees. v0.6.1 — Balance Tuning |
| Warlock tuning | No verified v1.0 numerical Warlock tuning obtained for this guide. | v0.6.1 lowers fire rate and damage per hit, without numerical values. It is a September note, not an October full-release hotfix. v0.6.1 — Balance Tuning |
Why do some pages say 15 levels?
PRE-RELEASE / DEMO The 10 August developer preview says the full game “will feature 15”. OFFICIAL SOURCE The actual 13 October v1.0 release announcement says “12 unique battlefields”. We use 12 at launch. The older number is a development plan, not a second current campaign total. We have no evidence of a 15-battlefield v1.0 campaign. Giants, Direwolves, Lightning, and More — Dev Log #1 · Legion Breaker is Out Now!
Where does the itch prototype fit?
The full-release announcement thanks itch prototype players and Steam demo players separately. That is evidence of distinct development/distribution stages, not proof that every currently downloadable prototype build equals the Steam demo. Legion Breaker is Out Now!
The itch site encountered a security challenge during our current source check. We have not downloaded or tested a current itch build, so we do not assign it the demo’s exact features or a full-game build number.
Does demo progress transfer?
Unverified. The official material reviewed here does not establish a save-transfer guarantee. Do not delete or overwrite a save based on an assumption of compatibility. A reliable answer needs a current developer statement or a documented transfer test; neither has been obtained for this guide.
Before following an older guide
- Check the app: 4425980 is the full game; 4630950 is the separate Steam demo.
- Check the publication date and whether “final boss” means the demo ending.
- Compare the quoted tooltip with your own build; do not import old costs or damage values.
- When counts disagree, prefer the explicit release announcement to an earlier roadmap.
Next: read the upgrade tooltip examples or the boss diagnosis. The Legion Breaker guide ties the notes together.
