The Heiankyo Alien, developed on a personal computer and released in 1979 as an arcade game from Denki Onkyo, is now ported and arranged for Windows! Arranged version "Heiankyo Alien 3671" is a time-based game, overwhelmingly addictive and euphoric, with new features such as seven items buried in the field, various scoring tactics, simultaneous play for up to four players. More aggressive game strategy leads to more advantage! No matter how many times you get killed, the game is not over as long as you have time remaining, so aggressiveness pays off! Enjoy this extraordinary euphoric gameplay by demonstrating your aggressiveness.

Posts announcing an update, tagged as patch notes or not

How this is measured

Posts in a game's official Steam news feed that announce an update: tagged as patch notes by the developer, or plainly about a patch or a released update.

News checked every 30 days. Observed since 27 Oct 2026.

An announcement is not a build. Developers can ship updates without a post, or post about several updates at once.
Untagged posts are recognised from their words, so a few updates are missed and a few other posts may be counted. Tagged posts are marked Patch notes on the Updates tab; recognised ones are marked Update.
Older posts are being read back through each game's history, most played games first, so months before October 2026 fill in over the coming days.
