The Egyptians can upgrade their Fortified Walls to Citadel Walls in the Mythic Age. The upgrade costs 800 food and 500 gold. The research time is 50 seconds. Citadel Walls have 600 hit points more than Fortified Walls.
For the Greeks, the Fortified Wall is the final wall upgrade.
- When the player saves the game after researching Fortified Wall, upon loading that game, the wall upon selecting is viewed as "Stone Wall" despite the fact that the Wall retains the Fortified Wall appearance and upgrade.
