MARCH 1st, 2023 – Mainframe Industries, the studio formed by the talent behind some of the most iconic MMO experiences from the past twenty years, is excited to reveal its first title. Pax Dei is an immense, player-driven, social sandbox – an MMO with community and emergent gameplay at its heart.

Welcome to the fantastical world of Pax Dei. Inspired by the mythologies of the medieval era, Pax Dei aims to deliver an MMO experience that returns to the roots of the genre with a player-driven and community-focused design, updated and brought into the modern age in stunning visuals created using the Unreal Engine 5.

“With Pax Dei, we’re inviting players to a Dark Age of wonder, where myths are real, ghosts exist, and magic is not questioned”, said Reynir Hardarson, Game Director and co-Founder Pax Dei was created for open-world play in the truest sense, and we can’t wait to see how players engage with our world and watch their stories emerge.”

Open world sandbox
Pax Dei
invites players of all types to define their own goals and challenges. Designed to maximize player interactions and allow different play styles to complement each other, Pax Dei opens up a vast, mysterious, and beautiful playground that players can fill with their own stories.
Cooperative village building
In the relative safety of the Heartlands, players will find the perfect plot to raise their home. Here, life is peaceful, and clans can develop and prosper. Players must work together to grow their villages, engaging with extensive character customization and modular house-building systems. Everything in Pax Dei is produced by human labor and skill, and every player has a role to play and a contribution to make.
Challenging PVE adventure & PVP combat
Leaving the safety of home to explore the Wilderness, players will encounter legendary creatures, ancient mysteries, and increasingly difficult challenges. Here, they can also choose to fight other players to assert dominance for their clan. The glory, bounty, and secrets they bring back more than justify the risks. But as players soon discover, the further they journey from home, the stranger and more dangerous things become.
Everyone matters
Skinning a basilisk, choosing between war and peace, picking flowers: it all matters. In a fully player-driven world, all play styles connect and complement each other. Pax Dei welcomes players of every type to join the community and be part of the stories about to take shape.
Bringing a persistent world alive with Unreal Engine 5
Mainframe has fully leveraged ground-breaking advances in Unreal Engine 5, which has enabled the world to come alive in an expansive simulation teeming with life and stunning detail. The next generation Lumen and Nanite systems allow players to see vistas spanning miles with real explorable distant mountains, while being able to examine the tiniest details of objects in the world. Mainframe has augmented the engine with MMO-specific capabilities, enabling a persistent, seamless world that players can explore at a scale supporting thousands of other players.

Pax Dei will be coming soon to Steam for PC gamers and is in development for cloud gaming platforms to become playable on any screen.
