Edit SysML v2 models with Eclipse SysON, an open-source and web-based MBSE modeling tool.
An implementation of the OMG’s specification SysML v2: language concepts, REST API, and textual interoperability format
SysON was presented during the Vendor Roadmaps and Implementation Status session of the MBSE Workshop held as part of the INCOSE International Workshop 2025, in Seville, Spain, on February 1, 2025.
We're thrilled to share that we've already made significant progress toward our goals!
As demonstrated in the quick demo, SysON is up and running—packed with powerful features and designed with a strong focus on user experience.
The project is on the right track and is already generating considerable interest.

SysML was created in 2005 as a standard for model-based systems engineering (MBSE) to elevate the role of models as primary tools for communication and documentation.
With system complexity continuing to escalate exponentially, and Digital Engineering emerging as a pivotal pillar to address an ever-challenging world, SysML 2.0 has been specified as the next-generation systems modeling language to improve precision, expressiveness, and usability.
SysON’s objective is to provide System Engineers with super easy access to this new standard, at minimal cost and great ease of use, with the guarantee of interoperability with other open-source MBSE tools notably Capella and Papyrus.
This will be achieved through three means: the support of the SysML 2.0 standard, the use of state-of-the-art web technologies, and an open-source approach.
Earlier versions of the mod were notorious for crashing during the "1917" conquest or having broken medal rewards. The patched version stabilizes the AI and ensures that late-game triggers work smoothly. Key Gameplay Changes

The patch updates the academy system to feature iconic leaders from the Central Powers and the Triple Entente. Players can recruit and command legendary figures such as: (Germany) Douglas Haig (Great Britain) Philippe Pétain (France) John J. Pershing (United States) 3. Stability and Balance Fixes
Heavy emphasis on static field siege guns and howitzers, reflecting the devastating artillery barrages of the Great War.
Start the game and explore the new 1914-1918 scenarios. Conclusion
Early releases of the mod suffered from sudden desktop crashes during long conquest matches, unreadable text strings, and heavily corrupted save files. The patched version resolves these issues through several critical updates:
World Conqueror 3 WW1 Mod Patched: The Ultimate Guide to the Best Historical Overhaul
If you are looking for more, popular alternatives include the mod or the Hearts of Iron 4 mod for WC3, as mentioned on the World Conqueror Wikia .
: Look for mods with active community support. This can be crucial for getting help with installation, bugs, or questions about gameplay.
Compressed high-resolution textures prevent older mobile devices and emulators from lagging during intensive artillery bombardments. Revamped Gameplay Mechanics

Obeo is also preparing a secure cloud-based offering to provide SysON as a fully hosted SaaS solution, enabling users to access and use it without any deployment on their machines or servers.
Stay tuned…
Alongside the open source development of SysON, Obeo is working on advanced commercial features to support cutting-edge deployments for large-scale and/or mission-critical projects.
Stay tuned…The project team works in an iterative mode to deliver a new version every 8 weeks.
The first release of SysON, version 2023.12, was launched in December 2023 by Obeo and CEA List.
The SysON roadmap takes into account user feedback and needs identified as part of an Open Innovation approach.
For the next months, our main goals include:
In 2025, we will intensify our collaborations with industrial partners to elevate SysON to the forefront of SysML V2 modeling tool excellence
and prepare it for professional, operational, and large-scale deployment.
