This repository is a fork of Keriew/augustus with extra quality-of-life and bug fixes.
Upstream Augustus is the full Caesar III remake with gameplay options. We keep that base and improve it step by step.
All improvements below are on master. Short overview — details in doc/FORK_SUMMARY.md.
| Feature | Where |
|---|---|
| Frame profiler | Options → UI — sim / draw / frame time (ms) |
| Walker debug | Options → UI — click a walker for action, dest, path |
| House upgrade checklist | Options → UI (default on) — why a house won’t evolve |
| Blueprint | Ctrl+C copy · Ctrl+V paste · Ctrl+R rotate · Ctrl+M mirror |
| House heatmaps | Overlay menu: House needs, Food stocks, Missing baths, Entertainment gap |
- Warehouse / granary: correct free space + staffing / emptying hints
- Farms / industry: cart status line (waiting vs destination)
- Dock: right-click status lines (no ship, quotas, no storage, permission blocked)
- Multi-tile footprints (warehouse 3×3, forts) rotate/mirror correctly
- Color-only variants do not spin with geometric rotate
- Display scale: clicks match the hardware cursor (SDL2)
- House delete + Undo: no free-worker age re-roll
- Stuck cart pushers when storage rejects goods
- Partial deliveries keep remaining cargo
- Workshops re-route when full
- Warehouse counters stay correct after add/remove
- House evolve text no longer corrupted mid-game
- Warehouseman / depot / supplier / docker re-route when storage rejects
- Tax/wage mood cheese reduced (harsh rates at settlement still hurt mood)
- Depot order threshold no longer hits 0
- Build-over-walkers: ghost, walls, burning-ruin rebuild all honor the config
- Sentiment messages fire on threshold cross only (less spam)
- Storages accept goods at 50%+ workers
- Allow building when walkers stand on the tile

Alternatively, you can try Augustus in your browser. Note that you'll still need to provide a valid Caesar 3 installation folder.
The aim of this project is to provide enhanced, customizable gameplay to Caesar 3 using project Julius UI enhancements.
Augustus is able to load Caesar 3 and Julius saves, however saves made with Augustus will not work outside Augustus.
Gameplay enhancements include:
- Roadblocks
- Market special orders
- Global labour pool
- Partial warehouse storage
- Increased game limits
- Zoom controls
- And more!
Because of gameplay changes and additions, save files from Augustus are NOT compatible with Caesar 3 or Julius. Augustus is able to load Caesar 3 save files, but not the other way around. If you want vanilla experience with visual and UI improvements, or want to use save files in base Caesar 3, check Julius.
Augustus, like Julius, requires the original assets (graphics, sounds, etc) from Caesar 3 to run. Augustus optionally supports the high-quality MP3 files once provided on the Sierra website.
First, download the game for your platform from the list above.
Alternatively, you can build Augustus yourself. Check Building Julius for details.
Then you can either copy the game to the Caesar 3 folder, or run the game from an independent folder, in which case the game will ask you to point to the Caesar 3 folder.
Note that you must have permission to write in the game data directory as the saves will be stored there. Also, your game must be patched to 1.0.1.0 to use Augustus. If Augustus tells you that you are missing it, you can download the update here.
See Running Julius for further instructions and startup options.
Augustus changes are explained in detail in the comprehensive manual. Below you can find the links to the manual in a few language versions.
