From Steam’s client network, last checked . Builds before 21 Oct 2026, when we started watching, aren't listed. Patch notes are the developer’s update post from an hour before to a day after the build. Not every build gets one. How we count

Steam keeps no record of past build numbers, so before 21 Oct 2026 a game’s update history comes from its own Steam news: posts tagged as patch notes, and untagged posts that plainly announce a patch or a released update. Older posts are still being read in, most played games first. How we count
When They Arrived Alan went hunting in his grandfather's country house. There was an invasion of the aliens. Cities are destroyed. You need to use survival skills and ingenuity to survive and save the planet. Build, explode, explore the world, develop your skills, try all ways to stop the aliens invasion. "What would I do after the alien invasion?" It's a question you've probably asked yourself, and it's a question we want to help you answer!
