  • Identified and implemented fixes to address various reported crashes. If you continue to experience issues, please visit the official forum where you can provide a detailed description of the issue, any error messages that appear, and a copy of your dxdiag.

Over the past several weeks, we’ve been monitoring the performance of the game closely as more people play it than ever before. Today, we hope to implement several fixes that will improve the experience for as many players as possible.

As always, there is a vast array of hardware and software combinations to accommodate as we continue to polish and perfect the game, so we want to hear if you’re experiencing issues. Be sure to visit the forum or come say hello on Discord, where you can include as much technical information as possible so our team can dig into the problem.

We’ve made several updates to the campaign and missions screens to not only clarify your campaign progress and historical victories, but to give you something to work towards as you learn and master the game.

  • The Campaigns screen for each storyline now displays which missions within the campaign have been completed by displaying a medal next to the mission title. The color of the medal represents the highest difficulty level on which the given mission was completed:

🥉 BRONZE: Standard Difficulty
🥈 SILVER: Moderate Difficulty
🥇 GOLD: Hard Difficulty

  • Missions that were completed before this feature was implemented will automatically receive the Bronze-tier medal.
Campaign Progress Medals

  • Campaigns that are fully completed will display an overall completion medal based on the lowest medal earned within the campaign. For example, a campaign with five Gold medals and one Bronze medal will display a Bronze medal on the Campaigns screen.
  • The swords on the campaign screen which indicate the difficulty of any given campaign have been updated to accurately convey their challenge. Easier campaigns will display a single sword; moderate campaigns will be marked by two crossed swords; the most difficult campaigns will be marked with three crossed swords.
  • The voice-over audio for the El Cid campaign is now available in Castilian Spanish.
