The Sinclair Estate is a place of mystery. What was once a place of old money and built by a wealthy family has become little more than a cluster of decrepit buildings, buildings that hold a secret.
Sinthetic publicity burb

Sinthetic is a community-created King of the Hill map released during the Scream Fortress 2021 update. It is set on a mysterious estate owned by Annabelle Sinclair, over which the two teams reluctantly battle. It is a haunted version of the custom map Synthetic.

Occasionally, the Toastmaster, who is a reskin of the Skeleton King, suddenly appears on the top of the main capture point.

Sinthetic was contributed to the Steam Workshop.


  • Spawn yard: An open area located right outside the spawn. Spell Books often appear here.
  • Transitional Building: After the Spawn yard comes the Transitional Building, which is a simple structure with two entrances and two exits leading out to the battlefield.
  • Valley: In between the Transitional Building and the House is the Valley, a narrow pathway made of dirt. Medium health and ammo packs can be found here.
  • House: Directly across the Control point stands the House, a large, two story structure offering a great view and lots of ammo.
  • Flanks: The Flanks are two buildings which are located at both sides of the point, sandwiching the objective in between them. They contain a medium healthpack and a Pitfall.
  • Tunnels: A set of two underground tunnels connect the Flanks with the House.
  • Platform: Opposite the Flanks is an elevated structure overviewing the point.


The Toastmaster is voiced by MegapiemanPHD .
