Succubus Nightmare Launches on Steam Today — 3D Escape Puzzle Across Mansion and Cathedral with 25 Free-Camera H Scenes by LUNA GameArt

Taiwanese publisher Mango Party has announced that Succubus Nightmare, an adult 3D puzzle game developed by LUNA GameArt, is out on Steam today. Escape-room puzzling and stealth evasion sit in the same loop here, and the two sisters only get out by leaning on each other. The game ships with five languages (Traditional Chinese, Simplified Chinese, Japanese, English and Korean) plus Japanese and English voice acting

Two step-sisters dragged into an estate, and a lewd crest carved into the younger one

You play as Charlotte, the elder of two step-sisters, guiding her sibling step by step out of a mansion estate ruled by a succubus. The story opens with both of them seized and hauled into the succubus territory, and worse, a lewd crest has already been carved into Ai. The mystery clears up as you go, and the one behind it all turns out to be someone else entirely

Mansion and cathedral, two stages the sisters clear together

The game runs across two stages, the mansion and the cathedral. Getting out means the sisters have to work through the puzzles hidden across each scene together before an escape route opens up

Watch the controlled servants, and use the abilities you were born with

The sisters call on special abilities through prayer: scouting to locate enemies, mending to restore torn clothing, or slipping behind an enemy to knock them out

Every use of an ability builds Ai pleasure gauge. Once it maxes out the abilities lock up, and a crowd of enemies comes running, which makes venting it at the right moment a real part of the plan

Meet the cast

Charlotte, the elder sister from an exorcist family

She always puts her step-sister first, and she is the youngest generation of the church exorcist family. Being pure human, though, she has no special abilities of her own

Ai, the younger sister of ancient elf and human blood

She puts her step-sister first just the same. Born of ancient elf and human blood, her ears carry a few traits of the long-eared folk

The succubus who dragged the sisters into her estate

She turned an entire town into her own domain and pulled the sisters into it. Beyond simply indulging herself, there seems to be a scheme buried underneath

Get caught and face punishment, with 25 free-camera H scenes to unlock

The 3D H scenes let you look around freely from any angle, or cut to close-ups of the face, chest or hips. Toggles for the lewd crest, the degree of succubus corruption and the hairstyle are all yours to adjust
