The maps cover a wide range of horror themes, including ghosts, spider infestations, backrooms, fever-dream environments and a tribute to The Shining. The jam also incorporates new Halloween-themed content into Arcane Dimensions, including the Cultist from Blood, Pumpklings and the Pumpkin Lord boss.

Zombie and Thundergoose worked on bringing the Blood Cultist into Quake, while Xage converted textures from Blood. Razzzor contributed the Pumpkin Lord alongside his own map, while Sock worked on the Arcane Dimensions update and created the hub that connects the jam's maps.
The pack also includes a small score-based minigame that rewards players for destroying breakable objects throughout the maps.
