Augustus is a game engine reimplementation for the classic Caesar III, enabling you to play on modern platforms (like Linux / Steam Deck). It's a fork of another called Julius that focuses on accuracy, with Augustus aiming to improve the game with a number of changes.
Version 3.2.0 was released and here's some highlights:
- A warning is displayed when the game can't be saved.
- Added a yearly autosave option.
- Fulfilling the emperor's requests will now spawn cartpushers heading to Rome with the resources.
- Added walkers who deliver food from the supply post to forts.
- Added inverse direction option to right mouse click dragging.
- Added relevant advisor buttons to many message types.
- Added hotkeys for setting the map orientation to north.
- Added the option to display messages as alerts on top of the screen.
- Added the option to display the building grid.
- Farms, raw materials buildings, workshops and wharves now display the efficiency of the building.
- Added support for MPG video files. Create a “mpg” folder in your Caesar 3 install directory and place the MPG video files inside, to use them in-game instead of the SMK video files.
- Added play/pause button to sidebar.
- Added hedge/palisade gates. They are created by building hedges/palisades over the roads.
- Added purple variants of columns and pavilions.
- Added watchtower variants.
- Added medium statue rotation.
- Added gladiator statue.
- Added support for assets relative path to the executable.
- Added a support for saving high-res screenshots of the minimap.
- + a lot more.
If you wish to play it directly from Steam, you can use the Luxtorpeda project to run it which I've covered before in various articles like this guide.
