Quick answer
Expect about 30-40 hours for the average player to complete Star Wars Zero Company's main story campaign. That number comes from Bit Reactor lead producer Caydence Funk in the official Steam community Q&A, and the estimate depends on difficulty level and experience with the strategy genre. It is not a confirmed 100 percent completion time.
Main story estimate
The only solid public hour range right now is the developer's 30-40 hour estimate for the main story campaign. Use the lower end if you already understand turn-based tactics, read mission objectives quickly, and avoid repeated failed attempts. Use the upper end or beyond if you are new to cover, Action Points, Overwatch, Advantage, squad Bonds, and injury recovery.
Why your run may take longer
Zero Company is a tactical campaign, so time is shaped by planning and recovery rather than just cutscene length. Higher difficulty, Permadeath, Beskar Mode, mission restarts, careful Den management, and squad experimentation can all add time. EA Help also confirms that Operations and Tactical Missions can expire, which means players will make route choices instead of clearing every available activity in one simple checklist pass.
Exploration and side content
Official sources describe Operations as non-combat assignments on the Galaxy Map and Tactical Missions as turn-based combat encounters. Steam's Q&A and StarWars.com both describe small third-person exploration sections before some story battles, where Hawks can gain Intel or Advantage before combat. Those exploration segments are described as main-story-only, so they support a broader campaign feel but not a separate open-world hour estimate.
Completionist time
Do not publish a completionist hour range yet. Steam achievements, player trackers, and full trophy-roadmap data need more post-launch evidence before they can support a stable number. The official FAQ does say there is no New Game+ at launch, though later playthroughs unlock certain customization options, so repeat runs may matter for players chasing cosmetics or alternate squad experiences.
Replay and story structure
The official Q&A says there are no romance systems or branching paths, and that the overall story conclusion is largely the same for everyone. However, squad choice can affect Bonds, some story elements, and how the journey plays out. That means replay value is more about different squads, difficulty levels, Permadeath choices, and customization unlocks than about chasing separate endings.
What not to use as evidence
Early Steam review hour counts are not completion evidence because many reviewers are still mid-campaign or reporting performance notes rather than finished playthroughs. Until more reliable completion datasets exist, keep the page anchored to the developer's 30-40 hour main-story estimate and clearly label everything else as variable.
