影のダンジョン Steam版 — 価格・1.0内容・セール

What the 1.0 “Complete Official Version” includes

The official release is a complete package, not early access. It ships the full 160-level main story (30–50 hours, ending around character level 99–100), the complete equipment system with 1,000+ weapon affixes and 2,400 weapon-granted skills, and the Greater Rifts endgame with four difficulty tiers.

Rift-exclusive loot includes 370 talent skill runes and 6,800 equipment skill runes. Higher rift difficulties roll better rare items and more affixes, which is the main reason to keep playing after the story.

• 160 main-story levels · 30–50 hours · level 99–100 finish.
• 1,000+ weapon affixes in five categories · 2,400 weapon-granted skills.
• Greater Rifts: Normal, Master, Nightmare, Inferno.
• 370 talent skill runes · 6,800 equipment skill runes.

Is Shadow Dungeon worth it?

Honest verdict at launch week: Shadow Dungeon is a solid pick if you want a Diablo-style loot loop in a 2D package at a $8.99 price point. The 1.0 release is genuinely complete — 160 story levels, the full affix system, and the Greater Rifts endgame shipped together, which is rare for a $9 indie ARPG.

Temper expectations in two places. First, early community feedback on the demo was lukewarm in spots, and launch-week discussion on r/ARPG was skeptical of the marketing push — the game plays safer than its trailer suggests. Second, difficulty is on the easier side for ARPG veterans; the fun comes from build-crafting, not from demanding combat.

Buy it if: you enjoy experimenting with affixes, runes and class builds more than mastering hard mechanics. Skip it (or wishlist it) if: you need a long-horizon endgame — the rift grind is fresh and updates are frequent, but the meta is still settling. The free demo remains the cheapest way to decide.

• Price anchor: $8.99 with a 10% launch discount — cheaper than most lunch.
• Content floor: 30–50 hours of story before the rifts even open.
• Community signal: launch-week reviews trend positive-to-mixed; demo feedback was lukewarm but the 1.0 build is a different package.

Which “Shadow Dungeon” is this?

At least four different things share the name, and search results mix them together. This page — and this whole site — is about the 2026 dark-fantasy hack-and-slash ARPG by OO Cat on Steam, app id 4423580.

It is not the Shadow Dungeon area in Old School RuneScape, the shadow dungeon location inside the Roblox game Sailor Piece, or the mobile title Shadow Dungeon Battle Heroes on Google Play. A second Steam product with a localized “Shadow Dungeon” title has also appeared in search results, so always confirm the app id before buying.

• This game: Steam app 4423580, released August 26, 2026.
• Not: OSRS dungeon · Roblox Sailor Piece location · Shadow Dungeon Battle Heroes (mobile).
• Before buying: match the app id and the developer name OO Cat.
