About Warzone 2100: Post-Apocalyptic Open-Source 3D RTS

Warzone 2100 is a free, open-source 3D real-time strategy game that draws inspiration from genre classics including Total Annihilation, Warcraft, and StarCraft. Originally released in 1999, it drops players into a post-apocalyptic world where they lead "The Project" — a faction working to rebuild civilization through advanced research, base construction, and tactical combat. The game combines the large-scale warfare of Total Annihilation with the strategic depth and faction-driven progression familiar to fans of Warcraft and StarCraft.

One scene shows small red rectangular walls with metallic top railings positioned between rocky hills. Several scenes across the game show a circular structure with a central blue glowing spire surrounded by four black conical towers.
