Get Started in 5 Steps
- Pick one of the 4 classes — Necromancer is the smoothest starter; compare all four on the tier list.
- Set up 1.0's quality-of-life features — controller auto-target and the one-button buff key, covered in the beginner guide.
- Read weapon-granted skills from your first drops — the equipment page explains the 5 affix categories.
- Push forward, not sideways — drops scale with the map, not your level; pacing notes in the walkthrough.
- Hit the cap and enter the endgame — Greater Rifts and the Paragon tree open after the story.

FAQ
What is Shadow Dungeon?
Shadow Dungeon is a dark fantasy action RPG by solo developer OO Cat, with a retro visual style inspired by late-1990s RPGs. It released on Steam as a full 1.0 on August 26, 2026, priced at $9.99, and sits at Very Positive on Steam reviews.
Is Shadow Dungeon the same as the OSRS Shadow Dungeon?
No. The Shadow Dungeon in Old School RuneScape is a dungeon area in that MMO. This site covers the standalone 2026 Steam ARPG called Shadow Dungeon by OO Cat — they just share a name.
Is Shadow Dungeon multiplayer or co-op?
No. Shadow Dungeon is single-player only, per the official Steam page. There is no co-op, multiplayer or online trading — which also means no seasonal economy pressure, a point launch reviews praise.
How This Codex Is Kept
Shadow Dungeon Codex is an independent, unofficial fan resource for Shadow Dungeon players — not affiliated with OO Cat.
- How we verify: Every number on this site is checked against OO Cat's official Steam announcements — class counts, affix totals and rift tiers all cite the 1.0 release notes.
- Update cadence: Pages are re-checked within 48 hours of each official patch note; the update feed on the homepage logs what changed and when.
- What we don't do: We do not publish boss stats, drop rates or hidden formulas that the developer has not confirmed — no guessed numbers, ever.
