About This Game

A SOLO-DEVELOPED OLD-SCHOOL SCI-FI RPG

Exium: Theia is a solo-developed, old-school open-world action RPG set on a hostile world filled with forgotten ruins, dangerous creatures, warring factions, abandoned facilities, and the remains of an ancient civilization.

Explore Theia at your own pace, take on quests, scavenge for weapons and supplies, discover hidden locations, and piece together the secrets buried beneath the world.

🌍 EXPLORE THEIA

Beyond the settlements lies a vast and dangerous landscape.

Follow the roads or leave them behind as you discover abandoned homes, military installations, refineries, caves, mines, settlements, ancient temples, and other locations scattered across Theia.

Exploration can lead to valuable equipment, supplies, quests, lore—or something that would rather you hadn't found it.

⚔️ FIGHT TO SURVIVE

Theia is filled with threats.

Fight bandits, hostile soldiers, machines, mutated creatures, and other enemies using firearms, energy weapons, explosives, melee weapons, and equipment discovered throughout the world.

Weapons and armor deteriorate with use and damage, making preparation and scavenging important parts of surviving away from civilization.

🎒 SURVIVAL & SCAVENGING

Manage your health, stamina, hunger, and thirst while exploring the wasteland.

Search abandoned locations for food, ammunition, medicine, equipment, valuables, and useful materials. Craft supplies, maintain your equipment, upgrade your loadout, and prepare before venturing into more dangerous areas.

🏛️ UNCOVER AN ANCIENT MYSTERY

Something much older lies beneath Theia.

Ancient temples, strange crystals, forgotten technology, and the remnants of the Vanir point toward a history far larger than the settlements struggling to survive on the surface.

Follow the story and uncover what happened to Theia—and what may still be coming.
