Short answer

The Mortal Shell II Open Beta is a limited Steam build covering the opening hours of the full game - from the Prologue into the first explorable region. It is an in-development build (bugs and performance issues are expected), and full save progress does not transfer to launch. Beta players do unlock specific full-game rewards.

What you can play

According to the official Steam description:

• Begin as the Harbinger and possess fallen Shells
• Explore an early section of the open world
• Cleanse beacons
• Enter optional dungeons
• Face hidden mini-bosses and challenges
• Progress toward Magdalena, the Lady of the Woods

The store page meta description frames this as roughly the opening three hours of the journey.

Story framing (official wording)

You awaken as the Harbinger, a prophesied being sent to reclaim the blessed Ova of the Undermether from zealots and abominations guarding her unborn kin.

• Magdalena, the Lady of the Woods - a destination / figure on the early path

Practical tips before you boot the beta

1. Expect rough edges. The developer explicitly calls this an in-development build.
2. Report bugs through the official Discord channel linked from the Steam page.
3. Play for rewards, not permanent inventory. Treat gear and currency as temporary.
4. Push past Marrow Keep if you want the prologue-skip unlock at launch.
5. Look for Tiel if you want early hands-on with a confirmed sequel Shell.
