Final Dev Letter and FAQ
Tjena, Survivors! Well, we made it. Active development on Generation Zero is done, we've wrapped it up. GZ has been such an amazing project, an incredible world, and an absolute blast of a game that we're profoundly proud to be a part of. We’re so thankful to our team that dedicated themselves to build Östertörn, FNIX, and its deadly machines. This unique setting, story, and experience were brought to life thanks to a strong creative vision and unwavering efforts. Over nearly six years since launch, the game has continued to grow, and we're in awe of the shape it's taken. Not only did the story of GZ, FNIX, and Östertörn unfold, evolve, and finally end in such an epic conclusion, but so did the world, the machines, and the gameplay. However, GZ still retains much of its mystery. Questions surrounding the future of the machine network, the fate of Bolshakov, and the significance of Geneva and Boston remain unanswered. For now, we're hoping elements like the Rivals, Tyrants, Base Assaults and Defenses, Bikes, Companions, and Experimental Weapons keep you in the fight. If that’s not enough, there are still many hidden secrets across Östertorn to discover with your friends, and we’ve even heard rumors of something called the “Swedish Space Program” for those brave enough. The development journey started back in the spring of 2016 during the last stretch of theHunter: Call of the Wild. Amid a regular play session, crawling around the digital fields of our in-game hunting reserve, there was an undeniable feeling of nostalgia. It echoed back to childhood days playing "krig" (war) with make-believe weapons and hearts full of adventure. Though the 80s Cold War Sweden might have been worrying for adults, we remember it as magical. Our society was built around a collectivist spirit, and from Military to Civil Defense, there was a consistent presence and reminder that everyone had a part to play if the shit hit the fan. At the same time we were open to - and eagerly consumed - ...Read full article on Community Announcements (EW_Neko)Patch NotesOfficial
Showdown Update - Hotfix
Greetings Survivors! Before we left for the winter break, you may have seen us mention that we were looking into a few changes to the Showdown Update that would address some of the feedback we saw from the community after its release. This Hotfix is now available to our players on Steam, and will roll out for console players very soon. While the changes to Base Defense and the introduction of the new resources tested well with our smaller beta testing group, it's clear that it didn't quite land with the wider playerbase in the way we expected. We saw and listened to your feedback and we are happy to share with you some changes we think will keep this new mechanic interesting while making it more rewarding for all playstyles. We have significantly increased the amount of resources you receive from Base Defense missions, which we hope makes your crafting (and hoarding) a bit easier to attain. We also saw a lot of requests for ways to obtain them without needing to complete Base Defense missions. We heard you - Rivals and Tyrants can now drop small amounts of these resources. A Rival or Tyrant should drop resources roughly equivalent to half the resources you would get from doing an Easy Base Defense mission. Rivals can drop Refined Aluminum, Refined Tungsten, and Refined Uranium, while Tyrants can drop Phosphorous and Ethanol. Finally, we also increased the Base Defense structure health. We hope that together these changes make your resource hunting more varied and exciting! We have also fixed some critical mission progression bugs we discovered after the release, made several crash fixes, and polished numerous other issues and bugs we found through testing and player reporting. Here is a summary of the hotfix: Crash / Stability - General crash fixes and stability improvements. - Various performance improvements. Showdown Missions - Fixed a potential mission blocker in the radio tower for Exclusion Zone. - General tweaks to Showdown missions breadcrumbing, triggers an...Read full article on Community Announcements (EW_Neko)Community & EventsOfficial

The final, free Generation Zero update for the co-op FPS is a game changer
An alternate history 1980s Sweden where giant robots have taken over the countryside is, frankly, the last place I'd expect a survival FPS game to be set. And yet, Generation Zero has been home to just that since 2019. With so many survival games coming and going in recent years, Generation Zero has firmly planted itself as one of the best and most-supported entries in the genre. Sadly, however, the game's last update is about to drop. But there's a blessing disguised in that news, because this last patch makes some great changes, all to the tune of an 80% off sale.
