Diluvion, a deep sea exploration RPG by Arachnid Games and Good Shepard Entertainment, has just received a major update.

The game originally launched in February of last year to rather lukewarm reviews. Developer Arachnid Games has spent the past year and a half working to fix many of the most egregious issues, and the game has now been relaunched as Diluvion: Resubmerged.

The largest changes include a complete rework of the game’s UI and salvage and upgrade systems, which were the most commonly cited problems critics and gamers alike had with the initial release.

Resubmerged also features improved AI, better navigation tools, and new quests. You can read more about the relaunch here, and don’t forget to check out the new trailer above.

Diluvion: Resubmerged is available on Windows PC via Steam and GOG for $19.99, and it’s currently 75% off to celebrate the overhaul.

Here’s a rundown of the game:

Diluvion: Resubmerged has been rebuild from the ground-up and introduces brand new features which add more strategic depth to looting, managing your unique crew, and upgrading your different submarines to fit player’s needs- and playstyles.
