Cosmic Tactical Combat Simulator is a game level by Matthias "Masmblr" Peters for the open source game Unvanquished. This map is based on UTCSUD.

1. Download the map and its dependencies:

2. Place the .dpk file(s) into your pkg/ directory:

   • Linux: ~/.local/share/unvanquished/pkg/
   • macOS: ~/Library/Application Support/Unvanquished/pkg/
   • Windows: %AppData%\Unvanquished\pkg\

3. Start the game and navigate to: Server Listings -> Start Local/LAN game -> select ctcs under Map -> press Start.

• Compiled with new build presets of:
  • NetRadiant Q3Map (ydnar) - v2.5.17n-git-530b81e8
  • NetRadiant - v1.5.0 Apr 23 2026 18:38:1
• Due to engine lighting changes, level-wide lighting has been redone.
• Shader and texture changes.
• Brushwork changes, mainly adding more detail:
  • Both sides now feature an added shaft tunnel and a train docking station.
  • Railings have been added to many parts of the map.
• The interiors of the stage doors have been changed:
  • The center doors have been separated and now lead independently to the other base.
• The center area now features more piping and a small pump station.
• The number of boxes has been reduced.
• Added new ambient sounds (pump, fan, computer hum).
• Texturing is now sharper: the scale of many textures was reduced or they were replaced with higher-resolution versions.
• Some lamps now feature grates to create more interesting shadow casting.
• The advertisement banner texture was reworked and fixed (corrected faulty shader programming).
• Almost all other areas have been reworked to varying degrees.
• Source refactored

To build or modify this map, you need to clone the source along with its dependencies (submodules).

git clone --recurse-submodules https://github.com/Masmblr/map-ctcs_src.git
cd map-ctcs_src

Run the provided script for your OS to merge the dependencies into the project structure:

Linux / macOS:

chmod +x merge.sh
./merge.sh

Windows (PowerShell):

Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass

To load the map in NetRadiant and test it in-game, copy or link the contents of the src/ folder into your Unvanquished pkg directory:

• Linux: ~/.local/share/unvanquished/pkg/
• macOS: ~/Library/Application Support/Unvanquished/pkg/
• Windows: %AppData%\Unvanquished\pkg\

It should look like this: .../unvanquished/pkg/map-ctcs_src.dpkdir/

If you want to compile the map yourself:

1. Install NetRadiant (v1.5.0 or higher) and choose the Unvanquished game profile.
