Extinction Day: Community Feedback Update is now live!
Over the past 5 weeks we have been listening closely to your feedback and focusing on the biggest issues reported since launch. This update is one of our biggest so far and heavily focuses on onboarding, quality of life, performance, and stability improvements.
Many of these changes came directly from community feedback, so thank you for helping us improve the game.
Features and Improvements
• Save and Resume is now available during Campaign, Sandbox and Freeplay
• Added Autosave functionality. Autosaves now occur every minute and also trigger when leaving missions
• Full Tutorial and Prologue 1 rework. We completely revisited the onboarding experience to make the game easier to learn and understand
• Major performance improvements on Low and Medium quality settings
• Added Windowed mode options
• Added WASD camera movement support
• Added a full Keybind and customization menu
• Improved hard crash handling and added recovery state support from Autosaves
• Added the ability to replay completed Challenges
Bug Fixes and Stability
• Additional crash fixes and stability improvements
• Continued work on reducing rare hard crashes and improving recovery
• Multiple smaller fixes and improvements across the game
Future Work / Update 1.1
A lot of players have been asking when new content and abilities will arrive. Now that most of the major stability and launch issues have been addressed, we can finally begin shifting our focus toward new disasters and gameplay content.
With that said, the past 5 weeks have been pretty intense for both the team and myself (and honestly the last 3 years before that too), so I need to take a short break before jumping into larger content updates.
Update 1.1 is absolutely happening, but I do not have a specific ETA just yet. We will keep everyone updated as progress continues.
I will still continue monitoring feedback and pushing hotfixes as quickly as possible if needed.
Thank you again for all your feedback, patience and support.
Please consider leaving a review if you are enjoying the game. It really helps a lot.
Happy doomsday! :)
