The Mound: Omen of Cthulhu Features - Co-op, Madness and Ratings

The Mound: Omen of Cthulhu features list is short but specific: online co-op for up to four players, full controller support, and a set of comfort and audio options that the listing spells out one tag at a time.

The feature list the store publishes

Everything below is tagged on the official store page rather than described in prose.

• Multi-player, Co-op and Online Co-op, for parties of up to four.
• Steam Achievements and Steam Trading Cards.
• Full controller support, plus DualShock and DualSense controller support.
• Steam Cloud and Family Sharing.
• Camera comfort and custom volume controls.
• Playable without timed input.
• Subtitle options, stereo sound and surround sound.

There is no local split-screen tag, which is consistent with the store text pushing spatialised voice chat as the way a party coordinates.

Content descriptors and the 18 ratings

The listing carries two Steam content descriptors and a developer note, and the region boards largely agree with them.

Scheme	Rating	Descriptors on the listing
USK (Germany)	18	Drastic violence, horror, chats
PEGI	18	Violence
DEJUS (Brazil)	18	Extreme violence, sensitive themes, nudity
Steam Germany scheme	18	Drastic violence, offensive language
ESRB (US)	M	Violence, blood and gore
CSRR (Taiwan)	R	Violence, fear
IGRS (Indonesia)	Banned	Online interaction, violence, horror

The Steam note that accompanies ids 2 and 5 is that the game features intense violence, blood and gore. That note is the reason the store page carries a content warning, and it is the developer speaking, not a reviewer.

Languages and audio

Eleven languages are listed for the game: English, Italian, German, Spanish for Spain, Simplified Chinese, Korean, Japanese, Polish, Portuguese for Brazil, Russian and French.

Only English carries the full audio flag in the listing. That is a narrow audio footprint for an eleven-language release, and it matters for a co-op game where the party is expected to coordinate by voice.

The listing gives no language toggle, no separate voice language and no per-language audio note beyond those flags, so the audio question is settled by the single asterisk on the store page.

Store metadata and reception

The listing names ACE Team as developer and Nacon as publisher, and files the game under Action and Adventure. Steam reported 3,186 reviews on the store page at the time we captured the data.

The feature mix is coherent for what the store text describes: a party that talks over spatialised voice chat, plays with a controller, and reads subtitles while watching for threats that the listing says may not be real. The comfort tags, camera comfort and playable without timed input, matter more than usual in a first-person horror game where the surprises are scripted into the atmosphere.

Five screenshots and three trailers are published with it. What is not listed is any season pass, any roadmap and any post-launch content plan beyond the four attached DLC appids.

Where to go next

The achievements are counted and partly named on Achievements, the store data in a single table is on Cheat Sheet, and the expedition loop is explained on How It Plays.
