MULTIPLAYER

Sector Rot includes real cooperative multiplayer for players who want to explore, survive and fight together inside the same persistent world.

Multiplayer is currently available through LAN and Direct IP connections. It can also be used through virtual LAN applications such as Hamachi or Radmin VPN.

Current Version

Sector Rot Version Alpha 0.8.1

All players must use the same game version before connecting.

What Is Currently Supported

Players can:

• Host a persistent Open Co-op world
• Join through LAN or Direct IP
• Connect through Hamachi or Radmin VPN
• Explore the same world together
• Fight mutants and hostile factions
• Use weapons, items, containers, doors and terminals
• Complete actions inside a server-controlled world
• Respawn according to the selected lives setting
• Rejoin a world while the server is still active
• Continue playing after host authority is transferred

The host controls the authoritative world state. Connected players send their actions to the server, while the server synchronizes the world for everyone.

Hosting a Game

To host:

1. Open Multiplayer.
2. Choose Host Game.
3. Select or create a persistent world.
4. Configure the game mode, lives and connection settings.
5. Start the included Sector Rot server.
6. Share the displayed IP address and port with the other players.

The Windows release includes the required server component.

Players do not need to install Python or download a separate server package.

Joining a Game

To join:

1. Make sure you are using the same Sector Rot version as the host.
2. Open Multiplayer.
3. Choose Join by IP.
4. Enter the host IP address and port.
5. Enter the password when the world is protected.
6. Connect and wait for the world state to synchronize.

For LAN play, use the host's local IPv4 address.

For Hamachi or Radmin VPN, use the IPv4 address displayed by that application.

Direct Internet Hosting

Direct internet hosting may require:

• Allowing Sector Rot and the server through Windows Firewall
• Forwarding the selected TCP port in the router
• Sharing the correct public IP address
• Checking whether the internet provider uses CGNAT
• Making sure the selected port is not already in use

CGNAT may prevent direct hosting even when the game and firewall are configured correctly.

Hamachi or Radmin VPN can be easier for players who cannot configure port forwarding.

Important Limitations

The current multiplayer system does not yet include:

• Public matchmaking
• Official relay servers
• Automatic NAT traversal
• Automatic mod downloads
• Encrypted network traffic

A stopped world must be hosted again before players can reconnect.

A running server can continue accepting returning players, including the original host after authority has moved to another connected player.

Player Count

The multiplayer interface supports larger player counts, but the recommended range is currently:

8–32 players

The highest values should be treated as stress-testing limits. Smaller groups are recommended for normal cooperative sessions while multiplayer is still being developed.

Mods and Custom Maps

Every connected player must use compatible game data.

For modded sessions, players should have:

• The same required mods
• The same mod versions
• The same load order
• Matching custom maps
• Compatible configuration files

The server validates the game version, protocol and mod configuration before admitting a player.

For the first multiplayer test, use the official game content with optional mods disabled.

Recommended First Test

For the most reliable first session:

• Start with two players
• Use an official Open Co-op world
• Disable optional mods
• Use LAN, Hamachi or Radmin VPN
• Allow the game through Windows Firewall
• Confirm that both players use the same version
• Keep the server running while testing reconnection

After confirming that the basic connection works, larger groups and custom content can be tested.

Reporting Multiplayer Problems

A useful report should include:

• Sector Rot version
• Number of players
• Who hosted the game
• LAN, Direct IP, Hamachi or Radmin VPN
• Selected mode and world
• Enabled mods
• Exact error message
• What happened before the problem appeared
• Whether the server remained active
• Screenshots or logs when available

Example:

Alpha 0.8.1, two players, Radmin VPN, Open Co-op, no mods. The client connected and played normally but stopped receiving enemy updates after the host entered another sector.

Detailed reports make multiplayer problems much easier to reproduce and repair.

Current Development Goal

Multiplayer is being tested and improved alongside the rest of Sector Rot.

Current priorities include:

• Better connection feedback
• Improved synchronization
• More reliable reconnection
• Persistent co-op stability
• Performance during large encounters
• Clearer hosting and joining instructions
• Better support for custom maps and mods

Public matchmaking and easier internet connectivity may be introduced in a future version.

For testing groups, technical support and bug reports, use the Sector Rot Discord community or the Multiplayer section of the itch.io discussion board.

Thank you for helping test Sector Rot multiplayer.

MODDING & MAPPING

This topic explains the creator tools currently prepared for Sector Rot, what they support and what modders and map creators should understand before starting a project.

Current Game Version

Sector Rot Version Alpha 0.8.1

Sector Rot is still in active development. The creator tools are updated alongside the game, so mods and maps should always mention the game version they were created for.

Creator Packages

Two separate creator packages are currently available:

Sector Rot Modding Kit

The Modding Kit is intended for creators who want to modify gameplay systems or create new content using editable data files.

It includes:

• Ready-to-edit templates
• Reference files from the game
• Example content
• Validation tools
• Packaging tools
• Mod installation structure
• Modding documentation

Supported content includes:

• Classes
• Perks
• Achievements
• Weapons
• Ammunition
• Enemies
• Loot
• Containers
• Difficulty settings
• Environment settings
• Colors
• Icons
• Audio
• Campaigns
• Game modes
• Open Run configuration
• Player Guide content

Mods are loaded separately from the original game data. Modders do not need access to the original Sector Rot source code.

Sector Rot Public Map Maker

The Public Map Maker is intended for players who want to create custom ASCII maps without using the internal development editor.

It allows creators to:

• Create new maps
• Resize the map canvas
• Place terrain and gameplay symbols
• Add walls, floors and environmental hazards
• Place doors and terminals
• Add enemies and containers
• Configure loot
• Add player spawn points
• Create exits and map transitions
• Validate the finished map
• Package the map as a map-only mod

The Public Map Maker contains only the tools needed for public map creation. The internal Sector Rot editor remains a separate development tool.

How Mods Work

Sector Rot uses a data-driven modding structure.

A mod is installed in its own folder and contains only the files that it adds or replaces. The original game files do not need to be edited.

This makes it easier to:

• Install and remove mods
• Keep the original game intact
• Test different projects
• Share mods with other players
• Detect missing or invalid files
• Update mods for future game versions

Each mod should include:

• A unique mod ID
• A visible mod name
• The author name
• The supported Sector Rot version
• A short description
• The required data files
• Optional icons, audio or custom maps

What Creators Need to Understand

Sector Rot is still an Alpha project.

Systems, data formats and validation rules may change between major versions. A mod created for an older version may require an update before it can be used with a newer release.

Creators should:

• Keep backups of their projects
• Use unique IDs for custom content
• Avoid editing original game files
• Validate the project before packaging it
• Mention the supported game version
• Test the mod or map in a separate profile
• Include clear installation instructions
• Report tool or documentation problems

The included validators are designed to detect common problems such as:

• Missing required fields
• Duplicate IDs
• Invalid symbols
• Broken map exits
• Missing spawn points
• Invalid item or enemy references
• Unsupported file paths
• Incorrect package structure

Maps and Gameplay Mods

A custom map can be released by itself as a map-only mod.

A larger project can combine:

• Custom maps
• New enemies
• New weapons
• New classes
• Custom loot
• Campaign data
• New game rules
• Custom audio and icons

This allows creators to build anything from a single survival map to a larger custom campaign or gameplay conversion.

Creator Rights

The Sector Rot Modding Kit and Public Map Maker are free for creators.

Sector Rot will not claim ownership over original content created by the community, including:

• Custom maps
• Original writing
• Custom artwork
• Original audio
• New gameplay concepts
• Custom campaigns
• Original mod content

Creators remain responsible for ensuring that the content they use belongs to them or that they have permission to use it.

Mods must not redistribute the paid Sector Rot game or its complete original data as a replacement download.

Getting the Tools

The Modding Kit and Public Map Maker are distributed as separate ZIP packages.

Contact me through the Sector Rot Discord and mention what you want to create:

• A custom map
• A map pack
• A gameplay mod
• New weapons or enemies
• A custom campaign
• A larger conversion

I will provide the appropriate creator package, documentation and templates.

Support and Feedback

Use the Modding & Mapping section for:

• Tool support
• Documentation questions
• Validation errors
• Map feedback
• Mod compatibility
• Feature requests
• Sharing development progress
• Finding collaborators

The goal is to make Sector Rot modding transparent, accessible and useful for both new creators and experienced modders.

Thank you for helping expand the world of Sector Rot.

The gun sounds are not working, the main menu sounds are not actually getting applied, the in-game ones are different from the main menu + the sounds get mixed up, the player dosen't have sounds (weapons firing, or shouting, the SIN's have or enemies but player dosen't)
Sometimes i need to press twice for interactions to occur or double tap and hold for the Demons view.

O yea, definitely, some mechanics from swat4 cannot be reproduced in new games, so dynamics, the enemies, the swat member, the sniper, omg. 

It gives me a SWAT 4 vibe, gonna play this.
