KKnD2: Krossfire

KKnD2: Krossfire is a real-time strategy game set on a devastated Earth, where the Survivors, the Evolved and the Series 9 robots fight for control of the planet. You build and improve an army, secure oil to fuel it and battle rival factions across 51 open-ended missions.

Factions and armies

Each faction has its own personality and a range of air, land and amphibious units, with distinct strengths and weaknesses. The Survivors field high-tech armies, while the Evolved use mutant low-tech mastodons and giant scorpions. Series 9 deploys machines such as seeders and weed killers; other available units include anaconda tanks and enforcers.

Build and fight

You send mobile oil platforms to capture oil fields, then construct buildings such as the Machine Shop, Barracks and Research Lab to produce and improve your forces. You can also search for ancient technology bunkers and use the technology inside to change the course of a battle. The enemy’s intelligence can use technology, attack and defend for maximum damage, and retreat when a fight turns against it, without cheating.

Missions and editing

The game includes 51 open-ended missions and a mission editor for creating missions.

The 2026 update

The update adds online multiplayer through Steam, a new launcher for adjusting settings, windowed mode and playable resolutions up to 4K. It also fixes crash bugs and other known issues, improves modding support and updates the map editor for 64-bit operating systems. Restored content includes missing animation and original HD sound effects; French and German are selectable through the launcher.
