Skynet Tactics Editor is a visual, builder-style mission editor for Fallout Tactics. It reads the original .mis, .til, .spr and localization data and presents maps as editable isometric scenes instead of raw records.

Created by Skynet for fallout.czech-games.net.

• real tile and sprite rendering from an installed Fallout Tactics copy;
• four true isometric editing views with view-aware depth sorting;
• drag-and-drop catalog for floors, walls, scenery, characters and interactive entities;
• yellow hover targeting, Ctrl-click selection, snapped movement, single-item rotation, rectangular multi-selection, group copy and paste, deletion, undo and redo;
• character identity, statistics, equipment, inventory, item pictures, descriptions and prices;
• complete installed .ent inventory library with safe import of items absent from the current mission;
• safe inspection and editing of real nested .ent definition properties;
• vehicle crew links with linked occupants represented only once in the scene;
• selectable and movable overlays for the mission's real player entry and connected exit fields;
• editable Lockpick properties for compatible doors and Science difficulty for compatible terminals;
• safe Save a copy workflow followed by an immediate parse verification;
• preservation of data the editor does not understand.

The application interface is English. Detailed documentation is available in English and Czech.

• Windows 10 or later;
• .NET 10 Desktop Runtime for a packaged build, or the .NET 10 SDK to build the source;
• a legally installed copy of Fallout Tactics. Game data is not included.

Open Skynet Tactics Editor.slnx in Visual Studio and build the Release configuration, or run:

dotnet build "Skynet Tactics Editor.slnx" -c Release

The application can be started normally and a .mis selected through Open map, or a .mis path can be passed as the first command-line argument.

Always edit a copy. Save a copy never needs to overwrite the source mission and reopens the generated file to verify its header, compressed stream and parsed sections. A successful save proves structural readability, not gameplay correctness; test every edited mission in Fallout Tactics.

The editor displays only properties that actually exist in an entity. For example, a RotatingDoor may expose Lockpick fields and a ScienceSwitch may expose Science difficulty, while a scripted gate or terminal may have neither. The editor does not invent unsupported fields.
