Barotrauma: Take On Several Roles Aboard an Armed Submarine in this Co-op Sci-fi Simulator

Barotrauma is a cooperative sci-fi submarine simulation set in the ocean depths of Europa, one of Jupiter’s moons. Players take on different crew roles aboard a heavily armed submarine, navigating through the hostile, pitch-black waters filled with alien sea creatures, environmental hazards, and internal crises. With its emphasis on teamwork, physics-based mechanics, and emergent gameplay, Barotrauma delivers a mix of survival horror, deep-sea exploration, and chaotic multiplayer interactions.

Plot and Setting

In the near future, humanity has colonized Europa, where the surface is uninhabitable due to extreme radiation. The only way to survive is by traveling beneath the moon’s vast frozen ocean, where underwater colonies, corporate factions, and mysterious ruins exist in the crushing abyss.

Players are part of a submarine crew, tasked with transporting cargo, conducting research, hunting dangerous creatures, or engaging in faction warfare. However, the ocean depths are teeming with monstrous lifeforms, hostile crew members, and unpredictable dangers, making every mission a high-stakes journey into the unknown.

Using a 2D side-scrolling perspective, Barotrauma has a gritty, industrial aesthetic, emphasizing the claustrophobic interiors of the submarine. The dark ocean outside is ominous and unpredictable, with blinking sonar screens being the only way to detect what lurks in the depths.

The sound design is filled with muffled alarms, distant sonar pings, and deep-sea creature noises, creating an ever-present tension. The music is atmospheric and unsettling, enhancing the feeling of isolation and paranoia.
