Undying Flame Release Date 2026, Gameplay, Platforms & System Requirements
The fire is your life. When it flickers, you panic. When it burns bright, you feel invincible. That is the simple but brilliant premise of Undying Flame, a top-down wave-survival roguelite that puts a campfire at the center of everything you do.
Developed and published by Per Sidera Industries, this is a game where creatures emerge from darkness to attack your fire. You must fight them off, collect the wood they drop, and feed it to the flame. If the fire dies, your run ends. There is no traditional health bar. Your condition is communicated through the fire’s brightness, sound, and size. It is a fresh take on the survivor-like genre that combines wave survival with resource management, tower defense, automation, and deep roguelite progression.
The game is set to release on September 8, 2026, for PC and Linux via Steam. A free demo was released on June 4, 2026. Here is everything you need to know about Undying Flame.
