So far only a handful of PlayStation games are on Steam, but it looks like a lot more could be coming to the store soon.
Unlisted PlayStation Games On Steam
Sony has created their own PlayStation curator's page on Steam, as a hub for all of their releases.
So far, only four PlayStation games are listed on Steam, Horizon Zero Dawn, Predator: Hunting Grounds, Helldivers, and the upcoming Days Gone port.
There are also 21 pieces of DLC available to purchase for Helldivers, taking the total amount of PlayStation products on Steam to 25.
However, if you look at the About section it states that there are 41 games on their list.
So, that means that 16 games and/or DLC are currently adding to their list but not visible on Steam.
As of right now, no other games have been confirmed to be coming to Steam, but there are plenty of games to choose from, both older titles and upcoming games.
Microsoft has been ahead of the curve when it comes to bringing their games to PC, which makes sense considering they own Windows.
It is possible that we could see upcoming games such as God of War 2 and Ratchet & Clank come to Steam as a way to tap into the market of gamers that play exclusively on PC.
While Sony has chosen not to participate in E3 this year, instead they will be focusing on their own events.
But, most companies who aren't participating are set to host their own events around the same time so it is possible we will see a new PlayStation event soon and it could be where they announce their expansion onto Steam.
