The Campaign is the single-player heart of ZeroSpace, a cinematic war story told through real-time strategy missions and role-playing choices. You command the Protectorate during humanity's seventh phase of expansion beyond Sol, navigating the politics and conflicts of the Orion Sector and its roughly ten alien civilizations.
Between battles you operate from the Mothership, where you upgrade your forces, talk with crew members, and decide how to respond to the people and factions you meet. Choices play out through interactive dialog and branching story paths, and they can change which Factions stand with you and how your crew feels about your leadership. The approach takes after classic narrative-driven role-playing games rather than a fixed, linear plot.
Mission Structure

The full ZeroSpace campaign is organized into three kinds of missions. Act 1 shipped with 12 of them at the start of Early Access, with the rest arriving on the road to the 1.0 release.
Mission Type | Count | Focus |
|---|---|---|
Main Story Missions | 15 | The central narrative of the Protectorate's war effort |
Hero Loyalty Missions | 10 | Personal missions that deepen ties with individual heroes |
Side Story Arc Missions | 15 | Optional arcs that expand the setting and offer extra rewards |
The table below lists the complete 1.0 campaign. The Early Access build opens with Act 1, a 12-mission slice of it, and further main story, hero loyalty, and side story missions are added through Early Access updates until the full count is in place at 1.0.
Difficulty
You can match the Campaign to your comfort level by choosing one of four difficulty settings: Casual, Normal, Hard, or Brutal. Casual eases the pressure for players new to real-time strategy, while Brutal is tuned for veterans who want the stiffest fight. The setting affects how hard the missions push back, so you can focus on the story or on the challenge as you prefer.
Choices and Consequences

Decisions made in dialog and on the battlefield ripple outward. Crew relationships, faction alliances, and story outcomes all respond to how you play, which encourages more than one run through the Campaign. Recruiting and developing your roster of Heroes and Commanders is central to progress, and several of them come with their own loyalty missions. See Crew and Recruitment for how your team grows.
