Studio WING's 1988 horror adventure Onryou Senki is out on Switch

D4 Enterprise released the 1988 PC-8801 horror adventure game Onryou Senki on Nintendo Switch today. It joins the EGGCONSOLE lineup as a direct port of the original computer release.

Most Japanese adventure games from the late 1980s were standard detective stories. Developer Studio WING took the familiar command-menu format and injected it with heavy occult horror elements. The result is a lot weirder than its peers. You play as Hiroyuki Kitahara. He gains spiritual powers after a supernatural encounter and uses them to fight vengeful spirits around Miyadera City. It blends standard investigation tropes with exorcisms.

Command-based exorcisms

The game relies on standard menu navigation. You pick text options to investigate areas, talk to NPCs, and fight ghosts. Because it's a direct port of a 1988 Japanese computer game, there is no English translation available here, meaning you'll need a solid grasp of the language to actually solve the deduction puzzles and progress the story.

The interface takes up about a third of the screen. The rest is dedicated to environmental art and character portraits. Navigating Miyadera City requires methodical investigation of every location. You have to speak to witnesses, gather clues, and figure out the specific weaknesses of the spirits haunting the area before attempting an exorcism.

The pixel art still looks great. The exorcism rituals feature some surprisingly neat visual effects for the hardware limitations of the time. You spend a lot of time staring at static character portraits, but the monster designs carry a genuine sense of dread. EGGCONSOLE releases usually do a good job preserving the original color palettes, and the harsh blues and reds of the PC-8801 hardware fit the horror tone perfectly.

Emulation quirks

EGGCONSOLE releases are straight emulation wrappers of the original PC-8801mkIISR hardware. This release lacks a scene select function, so you are stuck relying on the original save system. You have to commit to the retro pacing.

You can plug a USB keyboard into your Switch dock to play. It only officially supports Japanese 106, 108, and 109 layouts. I'm curious how clunky the text input feels on a modern Joy-Con if you skip the keyboard entirely, as playing an old PC game on a television is always a slight ergonomic compromise. The Switch port maps the most common commands to the face buttons, which helps speed up basic navigation around the overworld map.

A piece of Studio WING history

Studio WING is not as widely discussed in the West as companies like Falcom or Enix. They built an audience in the Japanese PC market by focusing on horror and science fiction adventure games. Onryou Senki is one of their standout titles. It eventually received ports to the MSX2 and PC-9801, but the PC-8801 original remains the baseline version.

Their games often prioritized atmosphere over fast-paced action. Onryou Senki forces players to read carefully and think about the lore they uncover. The deduction mechanics require actual thought, rather than just brute-forcing every option on the menu until the plot advances.

Bringing these regional computer games to modern consoles is exactly what Project EGG does best. The Switch is quietly becoming an excellent machine for 1980s Japanese computer history, provided you can read the text. The game is available now on the Nintendo eShop.
