404Sight is a free game made in support of net neutrality. It’s a 3D playground runner influenced by parkour running with the addition of a special ping ability that reveals areas that can speed the player up or slow them down. Hidden fast and slow lanes become visible, so it takes a bit of planning to plot a course through a world full of hazards – especially when the internet service providers themselves are actively trying to impede the player’s progress. In 404sight, the player attempts to traverse a level as quickly as possible without getting throttled by the ISPs, who actively throws slow tiles and inhibitors in their way.

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
