You've seen the clips this month. Skate 3 running inside Modern Warfare 2. Mario Kart in Call of Duty Zombies. Spider-Man swinging through Batman's Gotham. Old games are getting cracked open, decompiled and rebuilt by people working with AI, and the results are wild.
I watched all of it and thought about the game I actually love.
Wargame: Red Dragon has had the same maps since 2014. You've been able to rezone them, unlock them for 10v10 and nudge a spawn. You've never been able to make a new one. No editor, no tools, and the line for a decade has been that it will never happen.
Then I realised something. Software this vintage might be the easiest kind to crack. So on October 10th I sat down with Claude and Ghidra and tried.
The first test map loaded that night: flat ground, one road, 14 houses, three capture zones. It was ugly, and it was the first new map Red Dragon had ever loaded.
A week later, it's a 44 km donetsk meatgrinder.

>> How it works
It turns out the Mac version of Red Dragon shipped with its full debug symbols still inside: 312,000 function names, sitting in the binary since 2014. That's the Rosetta Stone. Every loader, every file format and every rule the engine uses to read a map could be found by name and read.
From there it was methodical. A map in this engine is about fifteen interlocking file formats: terrain mesh, heightmap, ground textures, the separate invisible ground units actually stand on, object placement, five navigation graphs (infantry, vehicles, air, boats, amphibious), capture zones, spawns and reinforcement routes. Every format got a reader and a writer. Every writer was proven by rebuilding the game's own files byte for byte before it was trusted to make anything new. All 2,659 of the game's data files now round-trip perfectly.
Then it got fun. Once you can write the files, you can generate a map: a city, a river valley, a circle, anything.
This isn't a mashup. Nothing was pasted in from another game. Every road, tree line, trench and building on this map was placed by a generator built for this game, running inside the engine Eugen wrote.
>> The mod: 3 Days to Kiev
A campaign in four chapters, following the war.
Chapter I: Hostomel. The airport assault and the woods north of Kyiv. Helicopters coming in low, air defence waiting. A historical map.
Chapter II: Mariupol. The siege. A dense port city and the steelworks. Helicopter supplies struggle to make it in. Also a historical reconstruction.
Chapter III: The Meat Grinder. The eastern front: Donetsk and Luhansk, trench lines, ruined towns, open ground and attrition. This map is playable today. It's still in the works, and I'm adding new things every day. This is more of a generic catch-all for this part of the war, not a specific place.
Chapter IV: Incursion. The cross-border raids into Russia. Ukraine on the attack.
>> What you can play right now
A 44 km front, built from scratch. It's the largest map size the game supports, packed with an industrial city of 3,300 buildings, mining towns, farm villages, trench complexes in different real-world styles, rail yards, 560 km of roads and close to 100,000 trees. Buildings are enterable, walls stop tanks, and everything can be destroyed.
Planes that land. This is the one I still can't believe works. Each side has an airbase with a 3 km runway, six parking stands and hangars. Your jets fly home, drop their gear, flare, touch down, roll out and taxi to a stand. They rearm there, then taxi back out and take off for the next sortie. While they're parked, they're on the ground and anything can shoot them. In twelve years, no Red Dragon plane has ever touched the ground. Getting there meant patching how the engine flies air units, not just editing data.
FPV drones. Both sides field FPV teams that hit like an RPG and can kill a truck full of infantry before anyone hears it. There are flying recon drones, plus electronic warfare vehicles that jam drones out of the sky.
Ukraine vs. Russia, 2022. Two new nations with full decks of about a hundred cards each. Russia brings Wagner Group infantry riding in light vans, waves of old artillery, T-64s and T-72s. Ukraine brings Soviet-era armour mixed with Western kit and drones everywhere.
