🔥 Steam Next Fest is Here: Play the Undying Flame Demo Now!

Undying Flame Demo · published 3 months ago

All eventsPlayers around this dateRead on Steam

The gates are officially open. Steam Next Fest has begun, and the playable demo for Undying Flame is live right now.

If you have been following our updates, this is your chance to step into the dark and test your survival instincts. We are incredibly excited to see how far you can get!

Here is what you will be jumping into when you download the demo today:

What is Undying Flame?

Undying Flame is a tense, strategy defense game built entirely around one core word: Defend.

Instead of watching a traditional health bar, you have to watch your flame. The fire itself tells you how you are doing. When your flame runs low, the darkness visibly tightens around the edges of your screen and pulses like a faltering heartbeat. 

You will start small. You will scrounge for wood, construct defenses, and upgrade your turrets to hold back the things hiding in the deep night.

If you protect your fire long enough, it outgrows the world. It will collapse and detonate into a newborn star where it stands. The map boundaries burn clean away, your camera zooms out, and your strategy will need to adapt.

Dive in and tell us what you think

We need your eyes, your feedback, and your strategies to make this game the best it can possibly be. Try out different upgrade trees, discover powerful synergies, and see how long you can keep the light burning.

Once you have played a few runs, hop into our community hub to share your thoughts, drop your feedback, or report any bugs you run into. Every piece of input helps the fire burn cleaner.

Go grab the demo, good luck out there, and let us know how far you can push your build! 🔥
