UnderMire Brings Co-op Roguelite Horror to Steam on November 13, 2026

UnderMire, the hand-drawn cooperative roguelite horror game from Table Knight Games, will launch for PC through Steam on Friday, November 13, 2026. The date was announced alongside a new trailer shown during the Cozy After Dark Showcase, offering a closer look at the strange subterranean world players will explore when the full game arrives.

The latest footage does more than put a date on the calendar. It introduces Rawiah, a newly revealed playable character who uses a tome to cast spells, while new key art confirms a four-person lineup comprising Hannah, Leo, Rawiah, and Sam. The trailer also provides an early glimpse of the Bunker's first layer, including a grassy biome and an encounter with the elusive Mothman.

A free playable demo is currently available ahead of release, giving prospective players an opportunity to sample UnderMire's unnerving co-op descent before its November launch.

A magical bunker beneath an English manor

UnderMire is built around a simple but effective horror-game premise: players descend beneath an old English manor into a magical Bunker that changes from run to run. It is a first-person online co-op adventure for one to four players, combining roguelite progression and replayability with tense exploration, monsters, environmental threats, and a deliberately odd assortment of objectives.

Each expedition is expected to ask players to venture deeper into the Bunker, confront creatures shaped by fear, navigate dangerous conditions, complete unusual jobs, and gradually uncover the mysteries hidden under the manor. The changing nature of the underground setting is central to the game's structure. Rather than treating the Bunker as a fixed dungeon memorized over repeated sessions, UnderMire positions it as an unpredictable space where routes, dangers, and opportunities can shift.

That framework puts the game in a space between cooperative survival horror and a run-based dungeon crawler. Players are not merely attempting to survive combat encounters; they must also contend with hazards, make use of whatever materials they find, and adapt when an intended plan breaks down. In a roguelite, uncertainty is often part of the appeal. UnderMire appears to lean into that idea by making improvisation a key part of its identity.

Rawiah joins the playable roster

Rawiah is the biggest character reveal in the new trailer. Her spell-casting tome suggests a more overtly supernatural approach than simply scavenging and brawling through the Bunker, though the specific spells, upgrades, and tactical limitations associated with her kit have not been detailed.

Her arrival brings the confirmed launch roster to four characters: Hannah, Leo, Rawiah, and Sam. Table Knight Games describes the cast as having distinct playstyles, an important element for a game designed around parties of up to four players. Different character roles can make cooperative runs feel more purposeful, especially when teams must react to changing enemy types, hazards, and resource shortages.

The full extent of each survivor's differences remains to be seen, but Rawiah's tome immediately establishes magic as part of UnderMire's wider toolset. That could prove particularly useful in a game where players are asked to adapt to unexpected situations rather than rely on a single ideal loadout. Whether playing alone or alongside friends, selecting a character may influence how players approach danger before a run even begins.

The Bunker's first layer includes a grassy biome

The new footage also reveals the first look at the Bunker's opening layer. Despite being buried beneath a manor, this initial area includes a grassy biome, reinforcing the game's magical and surreal direction. The setting is not presented as an ordinary concrete facility or a conventional haunted basement. Instead, the Bunker appears to contain environments that should not naturally exist below ground, making the descent feel stranger the farther players travel.

Changing biomes are among the game's stated features, alongside their own enemies and bosses. The grassy area is therefore likely to be one stage in a broader journey through the Bunker rather than a complete picture of the game's environment variety. It nonetheless establishes a useful visual contrast: hand-drawn greenery, underground mystery, and horror creatures occupying the same space.

One of those creatures is Mothman, seen in the new material. The famous cryptid is described as elusive in UnderMire's reveal, and its appearance gives the game another memorable supernatural presence amid its fear-fuelled monster roster. Details about the encounter itself have not been announced, including whether Mothman is a boss, a recurring threat, or something players may only encounter under certain conditions. For now, its inclusion adds to the sense that the Bunker is populated by entities drawn from an especially unusual nightmare.

Crafting through the SMUSH system

UnderMire's standout mechanical hook is its SMUSH system, which lets players combine everyday junk into useful equipment. The results can include weapons, healing items, explosives, and other survival tools. In a co-op roguelite, that kind of system can turn a bad situation into an opportunity, particularly when a group lacks the gear it hoped to find.

The emphasis on ordinary discarded items also fits the game's strange blend of domestic and supernatural horror. A magical bunker under a manor is already an unusual setting; making improvised equipment from miscellaneous junk gives its survival loop a tactile, playful angle. Rather than presenting every useful item as a polished piece of fantasy equipment, UnderMire asks players to make do with what they can gather and combine.

That design could encourage communication in multiplayer sessions. One player may discover components while another needs healing, ammunition, or a means of handling an approaching enemy. Because the game supports online co-op for up to four people, the SMUSH system has the potential to create the sort of rapid decisions that make shared roguelite runs memorable: save materials for later, create an immediate emergency item, or take a risk on an improvised weapon.

Fear is another resource to manage

Beyond health and equipment, players will need to manage a fear gauge. The feature is a natural fit for a horror game, but it also suggests that psychological pressure will have a gameplay role rather than serving only as atmosphere. The Bunker's monsters, hazards, and ever-changing environments may all push players toward difficult decisions as fear rises.

No detailed breakdown has yet been provided for how the gauge affects a run, what reduces fear, or what happens when it reaches a critical state. Even so, the mechanic signals that getting through UnderMire will mean more than defeating every monster in sight. Teams will need to account for their condition, their supplies, the terrain around them, and the possibility that panic or pressure changes how safely they can proceed.

UnderMire will also include proximity voice chat. That means communication is tied to where players are standing in the world, rather than functioning as a constant party-wide channel. In a game about entering an unstable bunker full of threats, proximity chat can make separation more consequential. A player who wanders ahead may be harder to hear, while groups that stay close can coordinate more easily but may also face danger together.

A co-op horror game built for changing plans

The central promise of UnderMire is flexibility under pressure. Its combination of shifting locations, distinctive characters, improvised crafting, hostile encounters, and fear management is designed around runs that do not always go as expected. A group can enter with a strategy, then find that a changed biome, a resource shortage, or an unexpected creature forces everyone to rethink the next move.

For solo players, that same unpredictability could make careful preparation and quick judgment particularly important. For groups, it opens room for role specialization, rescue attempts, creative crafting, and the occasional comedy that emerges when several people try to solve a frightening problem with whatever odd materials happen to be on hand.

The hand-drawn presentation gives UnderMire a visual identity that separates it from more realistic survival horror games, while its first-person perspective keeps players inside the immediate tension of exploring the Bunker. The newly shown grassy area and Mothman encounter indicate that the game intends to balance unsettling imagery with a more fantastical, eccentric kind of horror.

UnderMire release date and demo

UnderMire is confirmed to release on PC via Steam on November 13, 2026. No console, handheld, or other platform versions have been announced.
