About Undying Flame
When the fire dies, so do you. Undying Flame is a top-down wave-survival rogue-lite built around one living campfire. Creatures march out of the darkness. Shoot them. Collect the wood they drop. Feed the flame. Survive long enough to discover what the fire becomes. There is no health bar. The fire tells you everything. A healthy flame is bright, warm, and loud, with embers flying and logs crackling. A dying flame shrinks, dims to red, and goes quiet. Watch the color. Listen to the crackle. Feed it before it is too late. Choose three. Commit to a build. Every shop presents exactly three upgrades. Build around seven families: Rapid Shot, Multishot, Explosives, Piercing, Turrets, Hearth, and Guard. Each family branches into specialized upgrades and a mastery. Lock a card, reroll the shop, or spend now and live with the path you chose. During the Fire, you can commit to three families. Reaching the Star adds a random fourth family. Reaching the Void adds a random fifth. Four endless prestige tracks keep scaling across the campaign, so your build never stops growing. 91 relics. 10 synergies. 6 Ignitions. Every five waves, choose one of three relics across Fire, Bullets, Enemies, Economy
