There is something wonderfully satisfying about watching a kingdom grow from a handful of humble buildings into a formidable defensive stronghold, especially when you know everything you have built will soon be tested by an incoming army. That simple pleasure is at the heart of Thronefall, whose clever blend of kingdom management, tower defence and direct action makes its relatively straightforward formula so appealing. With Craaghelm, developer Mythwright takes that familiar experience into considerably darker territory, trading sunlit fields and medieval settlements for the volcanic depths of a fallen Dwarven kingdom. The result is an expansion that preserves what already works while introducing enough new ideas to make returning to the battlefield feel exciting again.
The premise gives this adventure a welcome sense of purpose. You are the last Dwarven King, a lonely figure carrying the hopes of a civilisation that has all but disappeared, tasked with descending into the mountain to reclaim the ancestral halls from a deranged mechanical army. There is a pleasing sense of history behind that objective, particularly when the few survivors at your disposal work from blueprints left by generations long gone. It is not a particularly elaborate narrative, but it provides an appealing backdrop for an expansion built around rebuilding, defending and gradually reclaiming something that was once yours.
Reclaiming the Mountain
The most substantial addition is a collection of eight new maps: Widerhall, Myrkforst, Brewerk, Lichtspalt, Grundsteg, Schattengrund, Tiefenlift and Zentrum. Each offers a distinct section of the underground world, giving the expansion a stronger visual identity than simply presenting familiar battlefields with a different colour palette. The transition from open countryside to enclosed mountain environments shifts the atmosphere considerably, with imposing stone structures, industrial remnants and volcanic hazards creating a more oppressive setting. There is a genuine sense that you are fighting through the remains of a once-magnificent civilisation rather than simply defending another collection of buildings.
More importantly, the terrain plays an active role in how each encounter unfolds. Moving platforms, lava streams and blocked choke points introduce complications that can make a seemingly straightforward defensive position considerably harder to maintain. The original game’s appeal comes partly from its ability to make relatively simple decisions feel meaningful, and these environmental hazards build on that strength. A carefully arranged line of defences might look perfectly secure, but a changing battlefield can force you to reconsider where your forces need to be and how much protection your settlement really has.
The new resources, Mithril and Energy Cores, also help distinguish the expansion from the original experience. Rather than simply relying on the familiar economic foundations, reclaiming the mountain involves using materials associated with the dwarven civilisation and its lost technology. This gives the setting a more convincing mechanical identity, tying the act of rebuilding directly to the history of the world. It is a small but welcome change, helping Craaghelm feel like a genuine new chapter rather than an assortment of additional levels.
A Familiar Formula with New Challenges
One of the smartest decisions is that Craaghelm does not abandon the basic structure that made Thronefall so enjoyable. The familiar rhythm of developing your settlement, improving its defences and preparing for an approaching attack remains central to the experience. There is still that lovely tension between making sensible economic decisions and ensuring your kingdom can survive whatever arrives after dark. The beauty of the formula is its accessibility: you can understand what needs doing without being buried beneath complicated menus, yet there is enough room for experimentation to make each decision feel worthwhile.
That balance becomes particularly important when the new environmental dangers enter the picture. Building an effective defence is no longer simply a matter of finding a comfortable position and filling it with enough protective structures. The layout of each map can influence how you approach the incoming threat, while hazards encourage you to think more carefully about positioning and flexibility. It is an effective way of making familiar systems feel less predictable without introducing unnecessary complexity.
The additional mutators provide another layer of difficulty for players who enjoy pushing their strategies further. Volcanic ash, natural disasters, boulders and other unexpected dangers can turn an otherwise manageable battle into a much more demanding affair. These modifiers are particularly appealing because they challenge established habits rather than simply increasing the strength or number of enemies. Players who have become comfortable with the original game’s routines will appreciate having reasons to reconsider their approach, although those who prefer a gentler experience may find some combinations rather unforgiving.
Dwarven Weapons and the Art of Defence
The expansion’s new arsenal gives the Dwarven King some interesting ways to deal with the mechanical opposition. Dragon’s Roar promises devastating close combat, providing an appropriately imposing weapon for someone attempting to reclaim an entire mountain. Twin Bastions takes a rather different approach, offering a pair of shields that emphasise protection and resilience. These additions help give the monarch a stronger connection to the dwarven setting, making the equipment feel like something recovered from an ancient civilisation rather than another collection of generic upgrades.
The defensive perks are equally important. Spiked walls can protect economic buildings, giving players another way to discourage enemies from disrupting the foundations of their settlement, while healing hot springs provide a welcome source of recovery during intense encounters. Neither idea fundamentally changes the structure of Thronefall, but both offer useful options when planning a defensive strategy. The best additions are often those that encourage a different way of thinking without making the original mechanics feel obsolete, and these perks fit that philosophy nicely.
There is also plenty to enjoy in the new military options. Axe Throwers provide a versatile attacking force capable of striking enemies on the ground and in the air, while Walker Tanks and Airships introduce a more technologically advanced flavour to the dwarven army. The contrast between traditional fantasy weaponry and steam-powered machinery is particularly fitting for a civilisation whose greatest achievements appear to have been buried beneath the mountain. These units expand the possibilities available to players and give the battles a more distinctive personality.
An Army of Mechanical Nightmares
Of course, rebuilding a kingdom would not be much of a challenge without something determined to destroy it. Craaghelm replaces the familiar opposition with an army of rogue Constructs, giving the expansion a different kind of threat to overcome. These mechanical enemies fit the setting beautifully, making the conflict feel like a battle against the remnants of technology that has continued operating long after its creators disappeared. There is something inherently unsettling about an army of machines carrying out its purpose without anyone left to control it.
Some of the more unusual enemies are particularly memorable. Loot Goblins threaten the economy and make protecting the settlement’s resources as important as keeping its walls intact, while Leap Bots add another disruptive presence to the battlefield. The Clockwork Oliphaunt provides a much more imposing spectacle, bringing considerable destructive potential to the enemy ranks. These different threats help prevent the encounters from becoming a simple exercise in repeating the same defensive arrangement, as players need to consider what each enemy could do to their carefully constructed kingdom.
The new heroes add another welcome dimension to the conflict. The Technician, Siege Engineer and Dwarven Spirit Warriors can be called upon to support the reclamation effort, bringing additional character to an army that would otherwise be dominated by buildings, towers and automated machinery. Their presence reinforces the idea that this is a desperate struggle involving the remaining forces of a fallen civilisation. It also gives players more opportunities to experiment with different combinations of units and supporting abilities, which is important in an expansion offering so many new ways to approach its challenges.
Presentation: A Beautifully Hostile Underground World
Thronefall has always benefited from its clean, attractive visual style, and Craaghelm shows how effectively that approach can be adapted to a different environment. The underground setting has a stronger industrial character, with stone architecture, glowing lava and mechanical structures giving the maps a distinctive atmosphere. The contrast between the warmth of the molten landscape and the cold appearance of the Constructs works particularly well, helping the enemy forces stand out against their surroundings.
There is also a practical benefit to the presentation. Strategy games need to communicate information clearly, especially when several units, structures and enemies are competing for attention at once. Thronefall’s uncluttered visual design helps maintain readability, allowing players to follow the action without having to fight against excessive detail. The new environments add personality without sacrificing the clarity that makes the original experience so approachable.
The sound design complements the setting, reinforcing the mountain’s mechanical and volcanic character. Metallic impacts, machinery and the general atmosphere of an industrial underground stronghold help give the expansion a stronger identity. Combat also benefits from satisfying feedback that makes each successful defensive encounter enjoyable, while the broader musical presentation supports the sense of a kingdom fighting for its survival. It is not an expansion that relies on elaborate presentation to impress, but its visual and audio choices work together to create a convincing setting.
A Worthwhile Return to the Throne
Craaghelm succeeds because it recognises that a good expansion should give players reasons to return without making them relearn everything they enjoyed about the original game. Its eight maps provide a substantial new setting, while the environmental hazards, additional resources, weapons, perks, units and heroes create plenty of opportunities to experiment. The mechanical enemies also give the conflict a distinct personality, making the battle for the mountain feel different from the original kingdom’s struggles.
There are a few areas where the experience could be stronger. Players who have mastered the original game may find the opening stages a little more forgiving than the toughest challenges they are accustomed to, which can make the initial return to the battlefield feel less demanding than expected. Some of the more specialised defensive options may also require further balancing, and occasional interface or enemy indicator inconsistencies can interrupt an otherwise polished experience. These are relatively minor shortcomings rather than fundamental problems, but they prevent the expansion from feeling completely flawless.
Nevertheless, there is a tremendous amount to appreciate here. The dwarven setting is a natural fit for Thronefall’s mixture of settlement building and defensive combat, and the new ideas are introduced with enough care to make the expansion feel like a meaningful addition. The moving platforms and environmental hazards encourage players to adapt, the new military options make experimentation rewarding, and the mechanical opposition gives the campaign a memorable identity. Most importantly, the experience retains the wonderfully addictive rhythm that makes it so easy to play just one more battle.
Thronefall: Craaghelm is a confident and thoroughly enjoyable expansion that gives the original game a fresh sense of adventure. Reclaiming a fallen dwarven kingdom is a satisfying excuse to return to the throne, and the combination of new maps, inventive hazards and formidable mechanical enemies makes the journey worthwhile. A few minor rough edges remain, but there is more than enough here to keep existing fans happily defending their kingdom long after the first descent into the mountain.
