About Fortify
Fortify is a real-time strategy game with tower defense elements. You defend your castle from attacking monsters and siege weapons using ranged and melee defenders, catapults, cannons, oil fields and more. You begin in the Iron Age, then advance to the Medieval Age and later the Imperial Age, with each age unlocking upgrades and new defensive techniques.
Game modes
The game includes two mission maps, an arcade mode where you try to survive for as long as possible, and player-versus-player multiplayer in a tower defense style.
In multiplayer, your opponent sends each monster that attacks you instead of enemies attacking automatically. You balance attack and defense to gain an advantage.
Other features
Fortify also features real-time lighting and shadows, achievements and leaderboards.
