UnderMire Descends Onto Steam November 13 — A Friday-the-13th Co-Op Descent Into the Bunker

You’re four floors underground, and the walls are breathing.

The flashlight flickers. Your friend’s voice crackles through proximity chat — closer than it should be — and somewhere in the dark, something hand-drawn and hungry is learning your name.

That, horror hounds, is the Bunker calling. And on Friday, November 13, the whole thing opens its jaws on Steam.

Charge your controllers and gather your bravest three — you do NOT want to descend alone.

Table Knight Games pulled back the curtain during the Cozy After Dark Showcase, and the headline double-whammy is hard to argue with: a firm release date — Friday, November 13, because of course it is — and a brand-new face joining the roster.

That new face is Rawiah, the fourth playable survivor, who trades melee for a spell-casting tome. She joins Hannah, Leo, and Sam, each with their own playstyle and tools for the ever-changing Bunker — a magical maze of biomes, bosses, traps, and puzzles hiding beneath an old English manor. Oh, and the Mothman is in there. (The Mothman. In the bunker. Of course he is.)

The signature system is called SMUSH, and it’s the kind of beautiful nonsense Harper lives for: combine everyday junk into weapons, healing items, explosives, and bizarre elemental contraptions. One person’s trash becomes another person’s arsenal. There’s also a fear gauge to manage — the Bunker feeds on your panic the way a popcorn horror sequel feeds on its own lore.

Full disclosure, up front, because that’s how we do things here: this is an announcement, not a verdict — Harper hasn’t descended into the Bunker yet, and nobody’s seen the full release. But a hand-drawn co-op roguelite launching on Friday the 13th with proximity voice chat chaos and a free demo already live? That’s a hook worth biting.

Harper’s Extras

• Phasmophobia — the granddaddy of scream-into-your-headset co-op horror.
• Lethal Company — junk-collecting chaos with friends, similarly SMUSH-brained.
• The Outlast Trials — co-op survival dread, minus the cozy hand-drawn charm.
• Harper’s full launch-week verdict when the Bunker opens — keep it locked on Think Horror.
• LIVING HELL — another co-op horror we’re tracking; the surprise Steam playtest is live now and a creator wants you aboard.
• our Hellraiser: Revival launch post — catch up on the launch-day coverage for another heavyweight horror release.
