About シンチカ - 新宿地下ダンジョン

Explore the underground city, a place where getting lost is commonplace, as your "target of conquest."

This is a dungeon-crawling game where you walk through a network of underground passages rendered in first-person retro 3D (using a custom raycasting engine, ChikaCaster), completing quests, increasing your exploration rate, and shaving off the shortest route time.

■ 30 Quests
"Go to that exit," "Go via this shop"—solve errands unique to the underground city using only your sense of direction.

■ Free Walk (Exploration Rate)
The fog clears only where you walk. A game of filling in a blank map with your own feet.

■ Time Attack + Ghost
Your personal best run runs alongside you as a ghost. Your route choices directly translate to time differences.

■ Encyclopedia and Titles
Collect things you find, proof of your completion. There are things to collect.

All areas, all quests, and all time attack courses are playable from the start.

Works completely offline. No ads or in-app purchases. Location information is not used.

*This work is a work of fiction. The map is a stylized layout based on a real underground shopping area and is not an actual map of the station. Do not use it for directions.
