Warhammer 40,000: Battlesector delivers fast‑paced turn‑based strategy in the grimdark 41st Millennium, letting you command iconic units and wield dozens of abilities.

01 / THE GUIDE

Age of Crimson Dawn Campaign

The Age of Crimson Dawn campaign offers twenty turn‑based missions set after the Devastation of Baal, focusing on strategic combat.

Players follow Sergeant Carleon and his allies as they purge the Tyranid infestation on Baal Secundus, defending Blood Angels honor.

  • Try focusing early missions on hero survivability.
  • Compare unit synergies before committing to a loadout.

02 / THE GUIDE

Skirmish Mode

Skirmish mode lets you fight on Baal maps of your choice, selecting both the faction you command and the opponent.

Before battle you fully customize your army list, choosing units, heroes, loadouts, and one of three objectives: Exterminatus, Conqueror, or Strategic Command.

  • Experiment with each objective to see how win conditions shift.
  • Balance hero abilities against unit composition for varied tactics.

03 / THE GUIDE

Planetary Supremacy

Planetary Supremacy is a conquest‑style skirmish campaign introduced in a free update, where you decide the planet’s fate.

Victory requires capturing more tiles, gathering strategic resources, expanding your army, then defeating foes in subsequent skirmish battles.

  • Prioritize tile control early to secure resources.
  • Compare expansion speed between factions to match your playstyle.

04 / THE GUIDE

Daemonic Incursion

Daemonic Incursion is a single‑player, last‑stand mode added with the Sisters of Battle Faction Pack, featuring endless daemon waves.

Khornate daemons spill blood, collect skulls, and overrun your forces; your sole objective is simply to survive.

  • Focus on positioning to limit daemon advance.
  • Use any available air support to thin incoming waves.

05 / THE GUIDE

Momentum & Air Support

Each faction possesses a unique Momentum system that can trigger a Surged unit, granting extra actions or ability upgrades.

Command Points let you call faction‑specific air support, such as the Blood Angels Stormraven missile barrage or Tyranid Harpy’s Sonic Screech.

  • Build Momentum early to unlock Surged bonuses.
  • Compare air‑support cooldowns between factions for optimal timing.
