Co-op guide
The whole campaign is playable together.
Steam lists online and shared/split-screen co-op, and NerveLabs says the entire game supports co-op. Since launch, saving and stability have both received fixes; Hotfix 5 also added teammate teleport from the map.

Consequences still need direct evidence
The store says players make consequential choices together, but it does not define host authority, client quest credit, save ownership, loot rules or what happens when partners choose different dialogue options. Those fields remain unverified instead of being filled from assumptions.
For a new co-op session, update both players to the same current build before diagnosing save or quest behavior.
