C1: MIDNIGHT LOOP

It is 2:00 a.m. It is raining. You are on the Inner Circular Route, and you have already been here before.

C1: MIDNIGHT LOOP is a first-person driving horror game set on a real stretch of Tokyo's Inner Circular Route, rebuilt from OpenStreetMap data: the elevated roads, tunnels and junctions, and about 19,000 buildings at their real heights.

One year ago tonight, your sister Mio vanished on this road. The late-night radio keeps telling you the same rules:

• If you notice anything wrong, take the next exit.
• If nothing is wrong, keep driving.
• Make the right choice eight times in a row, and the road will let you out.

Something is wrong on this road. Maybe a sign. Maybe the sky. Maybe the car next to you. And behind you, in the rear-view mirror, a woman with a red umbrella is running.

Features

• A real city at night. The route and its buildings are built from OpenStreetMap data. Wet asphalt, rain on the windshield, wipers, tunnels that swallow the sound.
• 40 anomalies across signs, lights, sky, traffic, the road, the car interior, the radio and the chase. New ones appear the longer you play.
• Difficulty that follows you. "Adaptive" watches how well you spot things and how steadily you drive, then adjusts how subtle the anomalies are, how often they appear, how fast the woman runs, and how heavy the fog is. Easy / Normal / Hard are also available.
• A real rear-view mirror. What you see in it is what is actually behind you.
• Three endings and an ending roll: tune the radio to 87.4 MHz on the quiet loops and listen to what Mio remembers.
• Unlockables: Endless mode, a dawn drive on the same road, gallery illustrations, an anomaly log, and S–D ranks.
• Cinematic look, with an optional VHS / dashcam filter.
• Play on PC or phone. Keyboard, gamepad, and touch controls; portrait or landscape.
• English and Japanese, voiced in both.

• On the last loop, always take the exit — and move to the left lane as soon as you see the Takaracho sign.

Comfort and safety

Includes jump scares and flashing effects. Settings let you reduce or turn off jump scares, reduce flashing, enlarge subtitles and turn on sound captions.

午前2時。雨。あなたは都心環状線を走っている。そして、この道を走るのは初めてではない。

『C1: MIDNIGHT LOOP』は、実在の首都高・都心環状線を OpenStreetMap のデータから再現した、一人称の異変探しドライブホラーです。高架、トンネル、ジャンクション、約1万9千棟のビルが、実際の高さで並びます。

1年前の今夜、姉の美緒はこの道で姿を消しました。深夜ラジオは、同じルールを繰り返します。

• 何かがおかしければ、次の出口で降りる。
• 何もおかしくなければ、走り続ける。
• 8回連続で正しく選べば、この道から出られる。

標識か、空か、隣の車か。どこかがおかしい。そして後ろでは、ルームミラーの中を、赤い傘の女が走ってきます。

特徴：実データの深夜の東京／全40種類の異変／腕前に合わせて変わる難易度／実際の後方を映すルームミラー／3つのエンディングとエンドロール／エンドレス、夜明けのドライブ、ギャラリーなどの解放要素／PC・ゲームパッド・スマホ対応（縦横どちらも）／日英ボイス／ジャンプスケアの強さや点滅の軽減など、遊びやすさの設定。
