Resident Evil 4 Remake is about to get new achievements on Steam, hinting that an expansion is on the way. While we can't see what these achievements are right now, they're likely related to either a VR mode or the Separate Ways expansion, as we know both of these are in the works.
This development was just spotted on Steam, and Capcom hasn't commented on the update. However, it seems very likely that we can expect an official announcement soon, especially if the achievements are already ready to go for whichever expansion comes first.
Judging from the chatter online, it seems that most fans have their hearts set on Separate Ways, the story expansion starring Ada Wong. This was originally available in the Resident Evil 4 base game, so it was disappointing to see that it didn't make it into the initial launch of Resident Evil 4 Remake. Still, that could just mean Capcom is (hopefully) spending more time to make sure it's ready for its release, and possibly even expanded from the original.
The VR mode wouldn't be amiss either. Capcom has been dedicated to this new way of playing Resident Evil for some time now, releasing both Resident Evil Village and the original Resident Evil 4 in VR. The studio had already made it clear that 4 Remake would be the same treatment, releasing it for free on PlayStation 5. Some had feared that this meant the VR mode would be exclusive to PS VR 2, but much like the original Resi 4, it could be on Meta Quest. It could also be available directly through Steam, if that's what this update is referring to.
If not, and it does stick with PS5 only, then it's almost guaranteed that the Steam update is referring to Separate Ways. It's unlikely that Capcom would just stick some new achievements into the base game for no reason, so it does seem like Ada fans are in for a treat sometime soon.
That being said, it is strange that neither project was shown off during Capcom's not-E3 showcase. This and a few other notable absences made it one of the weaker performances of the showcase season, as we were instead "treated" to the news that Pragmata has been indefinitely delayed... again. There was also time dedicated to Street Fighter 6 - a game that was already out at the time. No, we didn't get any word on DLC fighters either, so we'll just have to wait and see what happens there.
