How Ember Knights was Built from the Ground Up for Co-op

Before we even found the name and final concept for Ember Knights, we had already built a strong core combat loop centered around fast-paced hack-and-slash gameplay with tight controls. We then expanded on that foundation by introducing co-op, which ultimately gave rise to Ember Knights, available today for the first time with crossplay on Xbox Series X|S and Xbox on PC.

With the first closed beta and demo back in late 2020, we saw the appeal of the co-op element firsthand as friends, partners and community members played together. That’s when a core vision for our game took shape: a fast-paced, action-packed hack-and-slash roguelite that would feel just as rewarding solo as it would in co-op.

Based on feedback from the demo, we rethought our approach to run layouts – shifting from a free-roaming dungeon structure to a room-by-room design. We also redesigned the rooms so that, in most cases, all four players would remain visible on screen at the same time.

In addition to these structural changes, we re-evaluated the synergies between weapons, skills and relics to offer more meaningful collaboration. Each weapon plays a distinct role on the battlefield – from crowd control to short/long-range DPS to skill-based combos – and the same applies to skills. The goal was to create constant interactions and synergy between players.

For example, one player might equip the Rift Hammer, focusing on stunning enemies with powerful strikes and AOE skills like Rupture or Cyclone. Meanwhile, a teammate could wield the Guardian Bow, leveraging relics that deal bonus damage to stunned enemies.

This interplay only deepens as you experiment. Skills and relics interact in unexpected ways, encouraging teams to adapt their builds to complement each other’s strengths. Want to build a team of explosive pyromancers? That’s totally viable with skills like Molten Boulder or Ember Fire, and relics like Combustion Stone – which deals bonus damage when setting enemies on fire – or Fury Charm – which increases damage against burning enemies.

This design philosophy has guided us throughout Early Access, the 1.0 launch and beyond.

Community feedback post-1.0 has also played a crucial role in shaping the co-op experience. One common request was for an easier mode to help introduce the game to players new to the genre. Whether it was a hardcore roguelite veteran wanting to play co-op with newcomers, or a parent introducing their kids to the genre, Easy Mode was created to welcome more players into the experience.

Our ultimate goal has always been to make the game as accessible and fun to play together as possible. That’s why Ember Knights: Heroes of the Nexus Edition, released on October 16, includes full local co-op, online multiplayer and online crossplay between PC and Xbox Series X|S. Whether you’re sitting on the couch or syncing up with friends across the country, you can now jump into the Nexus and face the forces of Praxis – together.

Legendary warriors, the Ember Knights, are skilled in the wielding of the universe’s most powerful weapons, each with their own modification system!
