An hour ago, I published the store page for the upcoming DLC to Menace from the Deep, titled The Rift of Sanity.

You can read more about The Rift of Sanity in the previous devlog posts on Steam or directly on the DLC page. But the most important highlights of The Rift of Sanity are a brand-new playable character and the fourth act of the game — featuring entirely new enemies, increased difficulty, and a unique gameplay experience that sets it apart from the rest of the game.

The estimated release date for the DLC is June 25–26, 2025. All new game content is already complete, and the DLC will soon enter the testing phase.
Stay tuned for further development updates, and don’t forget to add The Rift of Sanity to your wishlist!

I'm happy to announce that work on Act 4 of the game is almost finished. The fourth act, titled "Outer World," from the upcoming DLC The Rift of Sanity, features a bunch of new enemies and a set of brand-new combat locations.

This game act will be pretty hardcore even for players who are well familiar with the game’s mechanics.

Since this act is narratively set beyond the Earth, there won’t be any travel locations like the Motel, Museum, or others. That means the set of non-combat travel locations in this act will be completely different.

Alongside the new hero, Act 4 has been the most content-heavy part of the expansion. Considering that both the new hero and the new act are now finished, it's safe to say that roughly 70% of the work is already done.

In addition to the new travel locations for Act 4, the expansion will also include a new travel location for the previous acts. I won’t reveal any details for now—just how it looks—but players who follow development closely can probably guess what exactly you’ll be able to do in this new location.

This still isn’t all the content that The Rift of Sanity expansion will include. Starting next week, I’ll begin work on a new set of inventory items, new Encounters, and some new modifications for Custom Game mode.
