In a decade-long evolution, a functioning multiplayer modification for Metal Gear Solid 5 allows two players to experience the game in unison, akin to skilled puppeteers controlling marionettes in harmony.
In a groundbreaking development for Metal Gear Solid 5 (MGS5) fans, a dedicated modder known as unknown321 has created Dynamite, a two-player co-op mod that brings a new dimension to the popular stealth game.
Dynamite's development journey began shortly after MGS5's 2015 launch, when unknown321 started reverse engineering the game's system, focusing on the weapon setups and unique staff mechanics, with the aim of creating a client/server emulator for handling FOB (Forward Operating Base) invasions cooperatively.
The project took a significant leap forward in 2023, with the release of Fuse, a functioning master server implementation for Dynamite. This was followed by a breakthrough, as another modding team revealed the network functions for connecting opposing players during FOB invasions. This collaboration and technical progress culminated in a functioning two-player co-op experience for MGS5 on PC, called Dynamite, in mid-2025.
Key challenges included reverse engineering encrypted JSON files and complex game data handling, creating a master server implementation for matchmaking and player connection, and tweaking gameplay mechanics designed originally for single-player or asynchronous multiplayer FOB invasions to work seamlessly in real-time cooperative play. Overcoming technical hurdles in client/server architecture and emulating MGS5’s network play functions were also crucial for the mod's success.
In its current state (as of August 2025), Dynamite offers a functional two-player cooperative mode, allowing players to experience the game together. This mod is available only on PC, and represents a significant milestone in MGS5 modding, enhancing the game’s open-world stealth and FOB invasion systems with cooperative play.
The mod is particularly significant as no official co-op mode was present in the original MGS5. As such, Dynamite effectively "cements" MGS5 as a spiritual successor to Peace Walker in terms of co-op gameplay. The mod arrives after a decade-long gap since the base game’s release, reflecting deep dedication by modders in overcoming various technical and gameplay design barriers.
Despite its bugs and unpredictable UI behavior, the raw experience of playing Dynamite with another player offers a unique charm. In chaotic gameplay, it can be challenging to distinguish between friendly and hostile enemies, leading to moments of frantic assault rifle fire and tranquilizer rounds. In some instances, players can even manipulate the game to perform actions that may not be intended, such as ripping an opponent out of a helicopter extraction.
Looking forward, the author expresses excitement about the potential development of Dynamite. With its roots in reverse engineering and community collaboration, Dynamite is not just a mod but a testament to the enduring passion of the MGS5 community.
