A few years ago, I came across a new designer named Wolfgang Klein (no relation to Alexander Klein) and his new company Assault Games. They create fantastic tactical level wargames and we have played several fo them and also got a chance to meet both Wolfgang and his friend and partner Erich Rankl. They are currently working on a new edition of their first game called Assault – Red Horizon ’41: Revised Edition and they readying it for a Gamefound campaign yet this spring. I reached out to Wolfgang to get some information about the revisions and changes to the game and he was more than willing to provide a lot of great information.

Grant: Wolfgang welcome back to the blog. It is good to have you on again and I wanted to thank you and Erich for playing Primosole Bridge with us last fall at SPIEL Essen. How has Assault – Red Horizon ’41 evolved over the past few years since its original release in 2021?
Wolfgang: Over the past 5 years, Red Horizon ’41 has evolved significantly through continuous development, community feedback, and extensive gameplay experience. What began with Rulebook 1.0 has gradually been refined into a much more mature and developed system. The new revised edition incorporates years of player feedback, integrates content from various expansions, and improves clarity, balance, and presentation across the entire game.
Over the past 5 years, RH41 has developed considerably, both in terms of the Assault System rules and its graphical presentation. In particular, with Sicily ’43 – Gela Beachhead (Rulebook version 2.0) and its expansion Primosole Bridge, we feel that we gained valuable experience that directly influenced the design of this revised edition and that will assist us in future volumes as well to improve the player experience and simulation value of the game.

Most of all, however, we are grateful for the intensive exchange we have had with our Assault fans over many years. We have remained very active in our forums on BoardGameGeek, and it is there that we have gathered, discussed, and evaluated a huge amount of positive and constructive feedback. With all the great ideas and contributions from our players, we have continued refining the rules step by step.
As far as version 2.5 is concerned, the door for feedback will remain open until the end of the upcoming Gamefound campaign.
In concrete terms, rules have been refined, adjusted, expanded, or removed. All texts have been revised to make them easier and more efficient to read. We have also made a clear step forward in wording and terminology. However, we have not changed the core gameplay mechanics. So players familiar with version 1.0 should still find it easy to get back into the system.
A detailed overview of the changes made to the system can be found on our website at the following link:

Grant: What is the upcoming new edition of the game? How has it changed?

Wolfgang: The upcoming version is referred to as a Revised Edition of Assault: Red Horizon ’41. It is not simply a reprint, but a comprehensive refinement of the system.
Major changes to the game and the Assault System include the following:
- Updated rules from Rulebook 1.0 to Rulebook 2.5
- Integration of rules and content from the TA / OAS (Tactical Air / Off-Board Artillery Support) Expansion
- Revised scenarios and a reworked campaign
- New terrain types
- Updated graphic design and artwork
- Improved components and markers
- New fortifications and obstacle elements
- A box inlay designed for the safe storage of all game components
Overall, the revised edition reflects everything we have learned about the system from our players and through continual play on our end since the original release. I do believe that the system will continue to evolve as other rule clarifications or needed changes come to light.
Grant: How did this opportunity for a new edition arise?
Wolfgang: After the original edition sold out, interest in the game continued to grow. At the same time, years of development, playtesting, and community feedback had accumulated.
In addition, RH41 is something like the core game for the Eastern Front within the Assault System. Our plan is to design an entire series of modules focused on the Eastern Front, and Red Horizon ’41 is the natural foundation for that planned series.
This created the perfect opportunity to bring the game back in a fully refined and improved edition rather than simply reprinting the original version.
Grant: How has the process of working with Sound of Drums been?

Wolfgang: I would describe it as a very special journey. We have now been working in cooperation with Sound of Drums for 3 years.
What makes this collaboration different from the traditional designer–publisher model is that we at Assault Games work with Sound of Drums on equal footing while maintaining our own independence.
The goal of this cooperation was to free ourselves from the typical publishing tasks such as production, logistics, and distribution, so that we could focus more fully on developing the Assault System and expanding into future opportunites. In many respects, this has worked very well. In other areas, there are still things that can be improved.
Sound of Drums, and Uwe Walentin in particular, has worked very hard to keep our backs free for designing by carrying the responsibility for taking care of the worldwide distribution network, logistics, and shipping. From my point of view, that works very well. Uwe is also a highly knowledgeable and perceptive figure when it comes to wargame design, and he has become an important advisor for us. His experience in the games industry helps us do things the right way — and focus on the right things.
One area of the cooperation where we have made major progress is in the structuring and preparation of our print files. I would especially like to thank Marc von Martial (Art Director at Sound of Drums) on this point. Thanks to his templates, we are now able to turn our designs into print-ready files in a much shorter time. That has been a tremendous help for Sicily 43, Primosole Bridge, and now also RH41 Revised Edition.
In the end, I would say that our journey is not over yet. Sound of Drums, like us, is still a young company, so there are new challenges every day. But as the saying goes: “Everything will be fine at the end of the road. If it is not fine yet, then the road is not over.”
Grant: Why have you wanted to amend or revise these various items in the game?
Wolfgang: We started the Assault System a long time ago as a new tactical game system, and from the very beginning it was clear that both the rules and the content would continue to evolve over time. Other systems refer to their rulebooks as “Living Rules,” and that is very much how we see the Assault System rules and the game as a whole.

At the same time, it is important to us that we do not do this alone. We want to actively involve our player base in the further development of the system so that it can become the best game system possible. Standing still is simply not an option for us.
Many of the changes were driven by years of gameplay feedback from the community and by our own experience with the system. Over time, we identified:
- areas where rules could be streamlined
- components that could be improved or added
- visual elements that could be made clearer
The goal was always to improve clarity, usability, and gameplay flow without changing the core identity of the system.
Grant: How has the graphic design specifically evolved? Who is the artist?
Wolfgang: The most visible aspect of the game’s development is undoubtedly the graphical redesign and the addition of new visual features. Michael Grillenberger, supported by Marc from Martial, once again did outstanding work, just as they did on Sicily ’43 and Primosole Bridge. I would like to thank them both once again for that work.
The map artwork in particular will immediately catch the eye. We have raised it to the same high standard seen in Sicily ’43 and Primosole Bridge, which creates an even greater sense of immersion.
Overall, the graphic design has been significantly refined compared to the first edition. Maps, symbols, counters, and other visual elements have been redesigned to improve readability and consistency. Vehicle artwork has also been updated, and the game’s entire visual language has been unified to create a stronger overall identity.

Grant: How does the artist’s style fit with your vision for the system?
Wolfgang: The visual style supports the core philosophy of the system: clarity, immersion, and functionality.
The artwork strikes a balance between historical authenticity and tabletop readability, which is essential in a tactical wargame where players need to process information quickly. In that sense, the artwork helps reduce the players’ workload so they can focus fully on the game and on the tactical situation on the battlefield.
Wolfgang: One major improvement is the integration of visual symbols directly onto the maps. Last year, we conducted a survey among our players because it was important for us to understand what they thought about the idea of including symbols on the map boards. The result was extremely close.
Many players were concerned that such symbols might reduce immersion. Because we take those concerns seriously, we decided on a more subtle compromise. Elevation levels and some terrain rules are now represented with discreet graphical indicators, allowing players to understand the battlefield layout more quickly without constantly consulting the rulebook.
That, in turn, makes things much easier for the players.


Grant: How have those changes made the game even better?
Wolfgang: Quite simply, these changes make the Assault System much more accessible and easier to play. The need to search for information is reduced, and the overall handling of the game becomes smoother.
In particular, readability, gameplay flow, and ease of learning have all improved. Players can now interpret terrain and elevation at a glance, which speeds up play and reduces rule lookups.

Grant: How have the graphics for the vehicles changed?
Wolfgang: The vehicle illustrations have been updated and refined, providing clearer identification and a more consistent visual style across all units. I think Michael also worked on them simply because he really enjoyed doing so.
These changes enhance both the historical feel and the table presence of the game.
Grant: Can you show us some examples of the new graphics as compared with the old?
Wolfgang: Certainly — here are a few examples:
- Updated vehicle illustrations
- Revised terrain
- Redesigned damage and smoke markers
- Improved map graphics





These updates create a much more cohesive and modern visual presentation compared with the first edition.
Grant: What new terrain features have you included in the system? Why were these important to include?
Wolfgang: The revised edition introduces several new terrain types:
- Wheat and crop fields
- Steep slopes
- Covered trails
These elements are closely tied to the historical landscape of the Eastern Front, particularly the region around Białystok in the summer of 1941. Large expanses of wheat and crop fields dominated the countryside and often influenced visibility and movement for advancing troops. During the opening phase of Operation Barbarossa, German and Soviet forces frequently fought across agricultural land where tall grain could provide concealment but also limit observation.

Steep slopes and covered trails reflect the natural terrain features of the area, which included rolling ground, wooded ridges, and narrow rural tracks. Such features often shaped the movement of infantry and vehicles, creating opportunities for ambushes or concealed manoeuvres.

Including these terrain types allows the game to better represent the tactical realities soldiers faced during the early battles around Białystok, while also expanding the range of strategic options available to players.
Grant: What are the new Fortifications & obstacle elements? Can you share examples of these counters?
Wolfgang: The system now includes additional fortifications and obstacle elements, allowing players to represent defensive battlefield preparations more realistically. These counters reflect the kinds of improvised and field-built defenses commonly used by Soviet forces in the border regions during the first days of Operation Barbarossa.

In June 1941, Soviet units attempted to delay the rapid German advance by establishing temporary defensive lines, often using field entrenchments, tank barricades, and hastily constructed obstacles. Barricaded roads and reinforced firing positions were typical features in defensive positions around key crossroads and villages. Although many of these defences were incomplete because of the speed of the German attack, they nevertheless influenced the course of local engagements.

By incorporating such fortifications and obstacles, the game is able to reflect the defensive measures historically present on the battlefield. These new counters expand the tactical possibilities in scenarios and campaigns, while also helping to recreate the atmosphere of the chaotic and desperate fighting that characterised the opening days of the campaign around Białystok.
Grant: How will the box be changed for this revised edition?
Wolfgang: The revised edition features an improved box design, including:
- A box inlay designed for sleeved cards
- A transparent lid for better organisation and visibility of components
These changes were made to improve both storage and usability for players. Many players prefer to sleeve their cards to protect them during repeated play, particularly in games with frequent handling such as card-driven tactical systems. The redesigned inlay ensures that sleeved cards fit comfortably inside the box without bending or compressing them, allowing players to keep their components protected while still maintaining a compact storage solution.
The transparent lid also helps players organise and identify the different components more easily. Counters, cards, and markers can be seen at a glance, which speeds up setup and makes it easier to keep the game organised during play. For a system that may include multiple scenarios and campaign elements, quick access to components is especially useful.

Overall, the improved box design reflects feedback from players of the original edition. By making the storage solution more practical and user-friendly, the new edition aims to make preparation, transport, and long-term storage of the game more convenient.
Grant: I know that you have covered this concept but I would like a bit more detail? Specifically, how have the overall rules for the game changed?
Wolfgang: The rules have evolved from Rulebook 1.0 to version 2.5, and possibly eventually to 3.0.
Key changes include:
- Integrated expansion content
- Clarified rules
- Streamlined mechanics
- Improved structure and organisation

Since the release of the original rulebook, the system has gradually developed through playtesting, player feedback, and the addition of expansion material. Earlier supplements introduced new mechanics and scenario elements that are now fully integrated into the core rules, allowing players to access the complete system without needing to consult multiple documents.
Another important goal of the revision was to clarify rules that had previously caused questions during play. Certain mechanics have been rewritten with clearer wording and additional examples, making it easier for players to understand how the system works in practice. This also reduces ambiguity during gameplay and allows players to focus more on tactical decision-making rather than rule interpretation.
The revised rulebook also streamlines several mechanics. While the core gameplay remains unchanged, some procedures have been simplified to maintain the fast-paced flow of the system. The intention was not to make the game less detailed, but rather to ensure that its mechanics remain intuitive and efficient during play.
Finally, the overall structure of the rulebook has been improved. Sections are now organized more logically, making it easier to locate specific rules during a game. Together, these changes reflect the natural evolution of the system and aim to provide both new and experienced players with a clearer and more accessible ruleset.
Grant: How have these changes improved the gameplay?
Wolfgang: The revised rules make the game:
- Easier to learn
- Smoother to play
- More balanced
Over the years, extensive playtesting and feedback from players helped identify areas where the original rules could be improved. Ambiguities in certain mechanics were clarified, and procedures that occasionally slowed down gameplay were simplified. As a result, the revised rulebook presents the system in a more accessible and consistent way, allowing new players to learn the game more quickly while still preserving the depth that experienced players expect.

The streamlined mechanics also improve the overall flow of play. Turns progress more smoothly, and players can focus more on tactical decisions rather than consulting the rulebook. This is particularly important in a fast-moving tactical system set during the opening stages of Operation Barbarossa, where battlefield situations changed rapidly and decisions had to be made under pressure.
In addition, the revisions helped refine the balance of the system. Through years of scenario testing and community feedback, certain interactions between units, terrain, and combat mechanics were adjusted to ensure that engagements feel both challenging and historically plausible. Together, these improvements create a more polished and engaging gameplay experience while remaining faithful to the original design of the system.
Grant: What is the timeline on the release of this new revised edition?
Wolfgang: The revised edition is currently in active preparation, and our immediate next step is the upcoming Gamefound campaign which is planned to start in May 2026. The campaign preview page is up and you can see that at the following link: https://gamefound.com/en/projects/sound-of-drums-gmbh/assault-red-horizon-41-rev-edition
As mentioned before, feedback on Rulebook version 2.5 will remain open until the end of that campaign.
Our goal is to use this period to gather final community input, complete the last refinements, and move the project into production in the best possible shape. A more precise release timeline will be shared as soon as the campaign and production planning are finalised.
Grant: Last but not least, what is currently in the design kitchen for Assault Games?
Wolfgang: Well, I think Assault Games might become a never-ending story. We will keep working on it as long as we continue to enjoy it—and that could still take a very long time.
Joking aside, we are very active when it comes to new ideas. I actually talked about some of this in our most recent SITREP (a bit of self-promotion here):
We have started publishing a development roadmap so that everyone can see what we are currently working on and what might be coming in the future. Of course, the roadmap only shows the official topics we want to share publicly—and yes, there are also a few unofficial ideas we are exploring behind the scenes.

To give you a small glimpse of what might be ahead, you can already see a draft cover for our upcoming Normandy journey. And that’s not all—there are several other things in development.

Thank you so much for your time in answering our questions Wolfgang and I look forward to future games from Assault Games and Sound of Drums.
