About Firestorm

Firestorm is a free modern-combat real-time strategy (RTS) game in your browser, in the spirit of the classic base-building RTS games. Build a base, keep its power grid running, move supply in from the field and send your army to break the enemy line.

You command one of nine real nations: the United States, China, Russia, India, Türkiye, Israel, South Korea, the European Union or Iran. Each fights its own way, with its own doctrine, units and signature power from the first minute, and AI opponents play their doctrine too. The nations are real; the hardware is not: every unit and weapon has an invented name. Battles are stylised, with no gore. It's an Etheria original, and every model, texture and sound is made in code.
