1 / 10HACHIKOMA is an anomaly-hunting game crossed with anime spinning-top battles, developed and published by ISEKAI Games. It launched on Windows PC through Steam on October 30, 2026 with a US$7.99 list price and a 10% launch discount.
You are stuck in Underground Passage No. 8, a loop of white tiles, fluorescent lights and yellow signs. If nothing looks wrong, you beat Hayate, a boy in a hoodie waiting at a street stadium, and walk on. If something is off, you turn back without fighting. Right calls raise the exit number; one wrong call resets it to zero.
It takes the anomaly-spotting loop fans know from The Exit 8 and bolts on a 2001-style battling-top game, complete with custom tops, a gachapon machine and a champion salaryman at the end.
Gameplay
Every loop is a judgement call. Scan the corridor for anything out of place among more than 40 anomalies, from posters that watch you to a train bursting through the wall or eight identical salarymen challenging you at once. Some only appear mid-battle, and shouting ANOMALY during a fight fills your spirit meter if you are right.
Battles have real depth. Three launchers, ripcord, string and trigger, each come with their own launch minigame. Once spinning, you steer your top, ram your rival and unleash a spirit technique. You build tops from a bit-chip, attack ring, weight disk, base and spin direction, then customise them with paint and stickers.
Three areas change the arena: the corridor, a platform where trains rush past mid-fight and a lobby where the stadium rides a moving walkway. A disposable camera holds 27 shots per run, and the film develops when the loop is judged.
Extra modes include Exit 0 with reversed rules, Endless and EXIT 88, which demands 88 correct loops in a row. There is a gachapon machine with 48 collectible bit-chip cards, a Twitch streamer mode, asymmetric co-op where a friend watches security cameras from a phone browser, and local two-player versus.
Story & Setting
Hayate has been waiting in Underground Passage No. 8 since the summer of 2001. You arrive to find him at a street stadium in the middle of an endless subway corridor, and the only way forward is to keep beating him, loop after loop, while watching for anything that should not be there.
Reach Exit 8 and you face the champion: Mr. Hachiman, the salaryman who has walked past you on every loop. Along the way a playable flashback lets you relive August 8, 2001 as Hayate, the day the loop began, and something waits behind a staff-only door. Japanese voice acting carries the anime tone, with English and Spanish subtitles.

Why it matters
Anomaly-spotting games exploded after The Exit 8, and most clones stop at walking and looking. HACHIKOMA earns its place by adding a full top-battling game with part-by-part customisation, which gives each loop an active, skill-based beat. Anyone who grew up on early-2000s spinning-top anime will feel the nostalgia. The streamer and phone co-op modes make it a strong pick for content creators. Skip it if you want pure horror atmosphere without the anime battle layer.
