What’s the download size?

The total download size for the demo is roughly 39 GB, so be sure to free up your storage space accordingly. The version includes several minutes of gameplay and two boss battles. Unfortunately, your save data will not carry over to the full game; otherwise, you could have gotten a head start in the single-player campaign.

That said, the experience should provide a clear picture of what the story is all about. You can also test out the fast-paced combat system that many find appealing.

Will there be a PC demo?

As of writing, the Lost Soul Aside demo is exclusive to PS5. It seems Sony currently has no plans to make the trial version available beyond the console. Moreover, the developers have been silent about the launch, so there’s little hope for PC users.

However, you can still look forward to the full version's launch on Steam. You can also expect to see an official announcement if a PC demo becomes available at a later date.
