Conan Exiles is an online multiplayer survival game, now with sorcery, set in the lands of Conan the Barbarian. Enter a vast, open-world sandbox and play together with friends and strangers as you build your own home or even a shared city. Survive freezing cold temperatures, explore loot-filled dungeons, develop your character from scavenging survivor to mighty barbarian and powerful sorcerer, and fight to dominate your enemies in epic siege wars.
Conan Exiles can be played in full single-player, co-op, or persistent online multiplayer.
After Conan himself saves your life by cutting you down from the corpse tree, you must quickly learn to survive. Weather scouring sandstorms, shield yourself from intense temperatures and hunt animals for food and resources. Explore a vast and seamless world, from the burning desert in the south to the snow-capped mountains of the north.
Forge the legacy of your clan as you fight to reclaim and dominate the Exiled Lands. Use the powerful building system to create anything from a small home to entire cities piece by piece. Wage war using swords, sorcery, bows, and siege weapons, even taking control of giant avatars of the gods to crush the homes of your enemies in epic battles.
SURVIVE IN A SAVAGE LAND
Dress well or light a campfire to stay warm and make sure to cool yourself down in the heat. Hunt, cook, eat, and drink to stay alive. Build a shelter to weather scouring sandstorms. Be careful when exploring darkened ruins or you might become corrupted by foul sorcery.
