In Whiteout Survival, a game developed by Century Games, players are tasked with building and maintaining a city in a harsh, freezing wilderness. This game, similar in concept to the survival city-builder Frostpunk but with a notably lighter tone, introduces a unique currency called Fire Crystals, which significantly alters the late-game upgrade path for players.
Fire Crystals are essentially a post-endgame resource, designed for high-level players. They are easily identifiable by their distinctive red-crimson color on the hotbar. The journey to acquiring these crystals begins when your city’s central building, the Furnace, reaches level thirty. At this point, normal leveling ceases, and the path to upgrading your Furnace through Fire Crystals opens up, spanning five levels from FC1 to FC5. However, the availability of these crystals is also dependent on the server’s active time.
Obtaining Fire Crystals can be straightforward but might require some investment. While they can be acquired through the Intel Station or claimed in a daily pack, these methods yield a limited number. The most efficient, albeit costly, way is purchasing them from the store. For those who prefer not to spend real money, special events occasionally feature Fire Crystals as rewards.
Beyond upgrading the Furnace, Fire Crystals can also enhance troops and other buildings. Upgrades using these crystals result in significantly more powerful outputs compared to standard versions. However, players should exercise caution and consider the potential for buyer’s regret. While buildings upgraded with Fire Crystals can be reverted, only half of the spent crystals are refunded.
