Early this morning, the busy Helldivers 2 Discord sent out a warning from the team. Imposters were threatening the integrity of Super Earth. Developers of several games on Steam had changed the name of their games to Helldivers 2, completely altering their Steam pages, including the developer and publisher tags. And Helldivers 2 was not alone in being targeted by this scam.
While games from different studios were altered, it seems likely this scam is being perpetrated by a single organisation, as the changes happened around the same time and the method was identical. The other games in these developers' catalogues also share a lot of similarities: they look like cheaply-made asset flips, and all of them are currently £39 or £49.
Once upon a time Valve was heavily criticised for its draconian approach to letting games appear on Steam. It was extremely picky. Steam Greenlight, which was a kind of precursor to early access, opened the doors a bit back in 2012, but now they're fully open, transforming Steam into the Wild West. The vast number of games available make discoverability a nightmare, and there's no real quality control. Asset flips, games that simply do not function—they're all given a home on Steam.
