Grafton Mansion is a survival horror story-driven singleplayer sequel to the Team Fortress 2 Community Map, "Crypto Forest" and a soft reboot of the timeline, continuing two weeks after the supernatural incident seen in Crypto Forest, from the point of view of a previously unseen character. 

The game's narrative is built upon the major story beats that Crypto Forest has set in place, but rewrites some elements of the story to better fit a new matured narrative for the universe moving forward, Grafton Mansion's story being written in tandem with a re-imagining of the original map's story, aiming for a singleplayer reboot of the original Crypto Forest in a similar vein.

Originally being developed as a singleplayer map for Team Fortress 2 utilizing vscript, Grafton Mansion is moving to a standalone sourcemod release to provide the cleanest possible way of experiencing the campaign.
