ZeroSpace Campaign Mode

The ZeroSpace campaign is the primary single-player experience in Starlance Studios' RTS+RPG hybrid, shipping with 13 missions at Steam Early Access launch on July 20, 2026. Each mission blends base building, hero combat, and narrative set-pieces where your decisions ripple forward—similar to the choice-and-consequence structure popularized by Mass Effect. You are not selecting dialogue wheels in isolation; branching paths change which allies appear in later battles, which side objectives unlock, and which tech shortcuts become available.

Campaign progression feeds your persistent hero and mercenary roster, so time spent learning faction mechanics here directly improves your readiness for Galactic War and skirmish. All four factionsProtectorate, Grell, Xol, and Legion—appear across missions as allies, rivals, or playable forces depending on story context. Seven mercenaries can be encountered and recruited through mission outcomes and optional objectives.

New commanders should pair campaign play with the campaign prologue guide and the full campaign walkthrough for mission-specific tactics, while returning RTS players may speed-run the opening acts to unlock loadout slots faster via the loadout builder.

ZeroSpace treats narrative choices as strategic resources. A diplomatic resolution in mission three might grant a passive economy bonus in mission eight, while an aggressive betrayal opens a harder combat route with unique mercenary access. The game surfaces consequences clearly in mission briefings so you are not guessing blindly, but second-playthrough discovery remains strong because mutually exclusive paths exist.

• Ally alignment —Support different faction leaders to unlock variant unit skins, dialogue, and mid-campaign reinforcements.
• Mercenary recruitment —Optional objectives gate specific mercenaries; see the mercenaries overview for kit summaries.
• Tech shortcuts —Story decisions can bypass portions of the tech tree in later missions, rewarding role-play consistency.
• Difficulty modifiers —Higher difficulties add enemy composition twists without removing story content.

Replayers chasing 100% mercenary collection should consult the walkthrough for branch requirements before committing to irreversible choices. Co-op players can experience many missions together via co-op mode, though some cutscenes may remain host-driven depending on build version at launch.

Missions escalate from tutorial-adjacent economy drills to multi-base sieges with hero duel finales. Expect familiar RTS beats—expand, scout, tech, push—but layered with hero ability timing and control tower contests explained in the control towers and tech trees guide. Early missions introduce one mechanic at a time; mid-campaign missions combine them under time pressure.

Boss encounters test loadout synergies more than raw APM. If you struggle, retreat to skirmish to practice a specific faction's production timing, then return with an adjusted mercenary pair from our loadout tier list. Hero death rarely hard-fails missions immediately, but recovery timers punish reckless diving—position your commander like a high-value unit, not an invulnerable action hero.

Campaign XP pacing is tuned so level-ups arrive before major ability checks, but optional side quests accelerate growth for players planning to jump straight into Galactic War Season Zero during its July 20–August 2, 2026 window.

Configure controls first: read keybindings and enable recommended quality-of-life options so muscle memory transfers to multiplayer later. Save before major dialogue forks if you want to explore outcomes on one account without full replays—ZeroSpace supports manual saves outside ironman-style runs.

Experiment with at least two factions across separate playthroughs or skirmish sessions; faction identity matters when campaign missions restrict unit rosters. Track release updates on the release roadmap because Starlance Studios plans additional acts during Early Access.
