If you’ve been playing Imperator: Rome and are wondering why you haven’t unlocked any achievements, it will most likely be the result of one simple oversight.
To enable achievements to be unlocked in a playthrough of Imperator: Rome, you must select Ironman Mode on the start-up screen. You’ll find it in the bottom-right of the screen. You can then play the game as normal – except now you will be able to unlock achievements.
A word of warning though: Imperator: Rome‘s Ironman mode is more hardcore than you may think.
Not only can you not use console commands (aka cheats), but the game automatically saves over its one save file as you play, meaning you can not exit and return to an earlier save after you have made a mistake.
