There exist four Game Modes in Barotrauma Multiplayer: Sandbox, PvP, Mission, and Campaign.
"A game mode with no specific objectives."
As the description suggests, there are no rules, no Missions, and no rewards in this Game Mode. The crew is free to do whatever they want in a random level seed, either for the purpose of learning the basics of the game or just for fun. The round ends when the crew reaches the end of the level or everyone in the crew has perished.
It is exclusive to Multiplayer.
"The players are split up into two separate subs, tasked with destroying each other."
In this mode, players are divided into two teams: Coalition and Separatists. Players can select their preferred team or allow the server to assign it automatically.
Both teams will play on a copy of the selected submarine with the Coalition, starting on the left side of the map, facing right (as players will be accustomed to from the other game modes), while the Separatists, starting on the right side of the map, will face to the left.
The round ends when all crew on either side are dead or unconscious, or if there are no more living players (i.e., only bots remaining).
PVP mode is exclusive to Multiplayer.
"The crew must work together to complete a single mission, such as retrieving an alien artifact or killing a creature that's terrorizing nearby outposts."
The players don't receive any rewards for completing the Missions, and the Game Mode is instead a way to quickly get into the action. The round ends when the crew completes the Mission and reaches the end of the level or everyone in the crew has died.
There are four Mission types available to choose from in the lobby, each with a multitude of different objectives:
- Salvage - Gather a logbook from a wreck, or an artifact from a cave or ruin.
- Monster - Eliminate creatures. They may be a swarm, or a single larger creature.
- Cargo - Travel to the end of the level without losing the cargo.
- Beacon - Activate a beacon station's active sonar. The beacon may be damaged, unwired or require a fuel rod to power it.
- Nest - Destroy creature eggs within a cave. Eggs are typically defended by a small group of their respective creature types.
- Mining - Mine minerals. Minerals must be delivered to the end of the level, and deconstructing them will fail the mission.
- Abandoned Outpost - Destroy creature eggs, rescue hostages or detonate the reactor of an abandoned outpost. The submarine is initially docked to the outpost, undocking will end the round. The submarine cannot be undocked before mission completion.
- Escort - Travel to the end of the level with escorted personnel still alive. They may become hostile, require special treatment or simply need to be kept alive, depending on the exact mission.
- Pirate - Eliminate the crew of a pirate vessel.
- Scan - Place scanners inside an alien ruin, and return them to the submarine when they finish scanning. Alien ruins may or may not contain guardians.
- Alien Ruins - Destroy guardians and their pods within alien ruins. Guardian pods can be detonated using attached alien terminals, or destroyed with weapons and tools.
If the host unticks all Mission types and starts the round, no Mission will initiate, meaning the gameplay will be very much like Sandbox.
Main article: Campaign
"Embark on a journey through the depths of Europa. Travel from location to location, complete missions to earn money for supplies, discover new biomes…"
This is the only Game Mode available in both Singleplayer Campaign and Multiplayer.
Upon choosing this Game Mode in Multiplayer, the host can choose to either start anew or load an old Campaign save. When starting a new Campaign, a Submarine that isn't an outdated modded Sub must be chosen and once the game starts, it cannot be changed in the server lobby anymore. All purchasable Submarines, which are available in the Shipyard, are selected by default. However, the host has the option to deselect whichever Subs they want to leave out of the game. Lastly, the save name must be entered in order to start the game.
The crew will then be taken into an explorable Colony and may begin their journey from there. The gameplay is similar to Singleplayer Campaign.
Traitors is a special function in Multiplayer. When enabled, depending on the Traitors setting, random players will be selected as the Traitors. They will be tasked with various objectives a few minutes after the game starts. Usually, Traitors start with searching for a specific item in a vent, locker or a supply cabinet. Once the item is obtained, the Traitors will be given further instructions. These instructions could be to sabotage specific installations, assassinate a specific crew member, and more.
