The primary goal in Barotrauma's Campaign mode is to maintain a Submarine and navigate it through the depths of Europa.

The ocean itself is inhabited by a number of aquatic creatures, as well as natural forming cave systems. The ocean also allowed for the creation of transportation shafts which interconnect the colonies throughout the moon. Beneath the ice layer is a vast ocean used as a transport network between colonies and as a source for natural resources. Due to the surface of the planet being too irradiated for survival, colonies and outposts have been established under the layer of ice covering the surface of the moon. The setting of the game is on Europa, one of Jupiter’s moons, which was colonized during the space age. Plot īarotrauma's time period takes place several hundred years in the future, during an era where humanity is technologically advanced enough to achieve manned interplanetary space travel. The game's wiring mechanic was inspired by Minecraft's redstone mechanics and MechComp in Space Station 13. The game's art style is said to be inspired by Link-Dead, a 2D side-scrolling shooter which had also been in development for a while before being presumed dead. The idea of having lovecraftian monsters be the main threat in the game most likely also inspired the enemies in Barotrauma as well. Several developers have attempted to make an actual game based on the concept, but so far none of them have been completed. The lab is then attacked by underwater sea creatures and it is then up to the player to try and escape the lab. The game woud've taken place in the depths of the Atlantic Ocean inside a research lab. Pressure is a game concept that originated from 4chan's video game board /v/. The horror aspects and underwater setting of the game were inspired by Pressure. The resource management aspects of the game were inspired by Space Station 13, and may have intentionally given Regalis the idea to make the game two dimensional rather than 3D. Barotrauma draws inspiration from several different sources. He would later begin working on an entirely new game which deviated greatly from his previous works. After the success of Joonas ('Regalis') Rikkonen's SCP - Containment Breach, he was encouraged to begin pursuing a career in game design and to start his own company, Undertow Games.
