Short answer

No multiplayer or co-op mode is currently announced. The official developer page and storefront listings describe Graveyard Keeper 2 as a single-player game, so buyers should not expect local or online co-op at launch unless that information changes.

Do this first

  1. Treat the game as single-player when deciding whether to pre-order.
  2. Watch official news for an explicit co-op announcement, not a wishlist or forum rumor.
  3. Recheck the platform feature labels near release because storefront metadata can be updated.

Why the answer is currently no

Feature descriptions focus on managing the graveyard, town, production, and zombie army yourself. Steam categorizes the game for single-player, while the developer's overview does not mention co-op, PvP, shared worlds, or online services.

Common source of confusion

The sequel features many controllable or assignable zombie workers and fighters. They are management units within the game, not other human players. Screenshots showing several characters therefore do not establish co-op support.

What would change this page

We will revise the answer if an official store adds multiplayer feature tags or the developer announces a co-op mode, beta, or roadmap item. Community requests alone are not confirmation.
