In Zephon, the world is in ruins and overrun by aliens. As a player, guide your survivors, develop your cities, and face your opponents in turn-based battles. But keep an eye on the dangers that surround you.

Developed by Proxy Studios, also known for Warhammer 40,000: Gladius, Zephon is a post-apocalyptic 4X strategy game in which you must guide survivors through a futuristic world plunged into chaos. And right now, it is priced at $13.99 on Steam.

You take control of humanity's last survivors and can explore three asymmetric paths or combine them. Build cities while managing the available space and optimize your economy using 11 different resources. You can also research more than 150 technologies to gain the upper hand over your opponents.

Battles in Zephon are turn-based, and you'll be able to command more than 50 different units. To emerge victorious, use your weapons and abilities wisely. If the situation becomes too dangerous, diplomacy may be your last resort to avoid defeat.

At the time of writing, Zephon has 1,977 reviews on Steam, 83% of which are positive. Players generally appreciate the inspiration drawn from Warhammer 40,000: Gladius. Its quests, story, and multiplayer mode are praised. Meanwhile, PCGamesN stated: "Civilization 6’s in-depth strategy and Frostpunk’s brutal vision of the apocalypse have a rival in a new 4X game."

However, the game seems to focus on combat at the expense of other mechanics. The AI has also come under criticism, and several players have encountered optimization issues. According to SteamDB, this 65% discount will end on November 4, 2026, and its price will return to $39.99.
