Quick answer: If a Graveyard Keeper 2 battle won't start, check the day: most battles only start on Sloth (the exceptions are Break Through to the Port and the sewer arena fights). Battles are picked at the blue/white shield icon on the map. Planting the banner doesn't start the fight: use the stand next to your starting control point and choose Start Battle, or the Start button in the barricade menu. To win, capture every enemy flag and hold it until the timer runs out. You lose if your health runs out or the zombies take your base.

Players ask this in several ways. How to start battle and how to star battle (a common typo) are the same question: where the start button is. Battles not starting and battle problem are usually the wrong day or a frozen timer. How to capture the flag is about holding a flag circle with your squad. German players search Graveyard Keeper 2 Kampf; the answers below are the same.

Quick facts

  • Day: Sloth, for most battles
  • Where: the blue/white shield icon on the map
  • Start: the stand beside your control point, or Start in the barricade menu
  • Win: capture every enemy flag and hold it until the timer ends
  • First battle needs: mercenaries, the magic bell and enough swords (12)

Before the first battle

Do Herbert's quests

Swords and Bell leads into the first fight (Herbert).

Pay the mercenaries

They're in the Barracks. In a 100-day playthrough: "There's mercenaries in the barracks… Pay for a battle." Hiring them adds 8 swords.

Make the magic bell

It forces the zombies to retreat if the battle goes badly.

Build barricades to reach the sword count

Herbert wants 12 swords. Use the build table on the right as you enter the Barracks. Barricades need reinforced planks: oil planks with melted fat and add bronze details. In a recorded 100% playthrough, three barricades took the count to 14.

How to capture the flag

Start it at the stand

Interact with the stand beside your control point and pick Start Battle.

Lead with the banner

Pick up a squad's red banner and the squad follows you. Drop it to leave the squad defending a spot.

Take and hold the flags

Keep the squad inside a flag's circle until it's captured. Capturing a flag clears the nearby green fog.

Leave a squad on each captured flag

Enemy zombies retake empty flags. Keep one squad on each flag and move a third between them.

ProblemFix
Nothing happensWait for Sloth
Can't find the battleLook for the shield icon on the map
Timer frozen at 3:50Use the Start button in the barricade menu
Not enough swordsHire the mercenaries and build barricades

If time still doesn't move, players fixed it by locking the frame rate to 30 FPS in the main menu, then opening and cancelling the barricade menu 2–3 times. Stuck in green fog or facing a closed gate? See the Central Districts Purge bug.

Sleep before battle day. The game saves only when you sleep, so a lost or bugged battle costs you just that day (How saving works).

How to make zombies fight

After your first win you get a shield that unlocks another squad. Give each zombie armour and a pike or bow (swords are player-only), carry it to the zombie pen in the Barracks and put it in the chains; lying on the floor doesn't count. Zombies don't gain experience from fighting, so level their combat perks with another job first.
