If you were awake in early this morning, you may have seen that Helldivers 2 was having a massive Steam sale. This was, in fact, an imposter. Another game in disguise, which was promptly delisted from the storefront after changing its name, key art, and developer information to mimic the popular sci-fi shooter.
According to SteamDB - a third party website in which ample information of Steam games can be viewed - the events that led up to this conclusion can be clearly seen. At 9:55PM ET, indie game Figurality had its name changed to Helldivers 2. Mere minutes before, the publisher and developer listed was changed to PlayStation PC LLC and Arrowhead Game Studios respectively.
Around the same time, the game's description was changed to mimic the official Helldivers 2 store page. The tags were changed, as were screenshots, trailers, assets and assosiations. Even an epilepsy disclaimer was added - paired with Sony and Arrowhead Legal info of course. It was here that a whopping 75% sale on the game was added.
