Sandevistan — Cybernetic "Speedware" Implant

Sandevistan adds an experimental neural implant to the game that temporarily accelerates the user’s perception and movement.

Once activated, the surrounding world slows down: enemies, creatures, NPCs, bots, and projectiles move more slowly while the user retains a speed advantage.

This is not a simple buff. The implant has its own visual and sound effects, works in both singleplayer and multiplayer, and excessive use gradually overloads the nervous system.

The world does not become slower. You become faster.

Requirements

LuaCsForBarotrauma is required.

Activate LuaCsForBarotrauma (check mod description how to do it) and turn on C# support in its settings by selecting:

C# — Enabled

Main Features

• Install Sandevistan as genetic material.
• Activate and deactivate it with the Z key.
• Locally slow down creatures, NPCs, bots, and projectiles.
• Accelerate the implant user.
• Real players do not slow each other down.
• Full singleplayer and multiplayer support.
• Bots can also use the implant.
• White afterimages, radial blur, and chromatic distortion.
• Unique activation, operation, shutdown, and overload sounds.
• Nervous system strain and psychosis mechanics.
• Gradual loss of control when the implant is overused.

How It Works

Once installed, Sandevistan can be activated at any time by pressing the Z key.

The implant has no standard timer or regular cooldown — the player decides how long to keep using it.

However, prolonged activation increases strain on the nervous system and may cause severe consequences from overloading the body.

High skills and certain medical drugs allow the user to maintain control for longer, but Sandevistan is never completely safe.

Multiplayer

The mod fully supports multiplayer.

• Other players can see the owner’s afterimages and accelerated movement.
• Real players do not slow each other down.
• NPCs, monsters, and bots react correctly to the slowing effect.
• The implant state is synchronized between the server and clients.

The mod must be installed on the server and by all connected players.

Where to Find Sandevistan

The implant cannot be crafted.

It is sold in limited quantities by:

• military merchants;
• research merchants.

Sandevistan begins appearing from the second campaign zone, starting at approximately 30% difficulty.

Price: 15,000 marks

Usually, only one implant is available from a merchant.

Compatibility

The mod does not replace vanilla characters, weapons, or the entire genetics system.

It adds a separate genetic material and its own mechanics on top of Barotrauma’s existing systems.

Mods that alter:

• global game speed;
• character animation updates;
• genetic materials;
• psychosis;
• screen post-processing;
• AI behavior;

may require additional compatibility testing.

Enjoy the mod, and please let me know if you encounter any errors or bugs.
