Barotrauma is a cooperative sci-fi submarine simulator that has been plodding its way through the murky depths of Early Access for the past three years, but is now getting ready for a 1.0 release this spring. This involves a "pre-patch" with "final fixes and changes" that the development team wanted to make before release day and the price rise two weeks later.
The most notable changes in this patch for many players are the reworked poisons and status effects, according to the developers. Some mods may be broken due to these changes, although they expect that the creators of these mods will have a chance to fix the problem before the release of version 1.0.
The improvements to poisons are quite substantial: they are now available on monsters, and the effect of poisoning is becoming more diverse.
Barotrauma will be priced on Steam in two weeks, on February 10th, according to a blog post. Steam is currently 80% off to "give everyone one last good opportunity to purchase the game before 1.0 is released." It is not known what the new price of Barotrauma will be after the release.
