About This Demo

CastleOn Scriptum is a tower defense game in which you protect your Keep either with static defences such as traps, gatehouses and towers manned by archers, crossbowmen and catapults, or by taking a more active approach and training different types of melee units like footmen and knights and slaughtering enemy up-close.

Defend your Keep

Stop the enemies from reaching your keep! Build towers and train over 20 different types of ranged units. Rain fire and arrows upon them!

Command your Armies

Train over 20 different types of footmen and knights, or hire various mercenaries to battle the invaders!

Place Traps

Killing pits, caltrops, boiling oil, rolling logs, moats and many more fun traps are at your disposal!

Manage the Economy

Make the peasants harvest gold and lumber! Construct farms, blacksmiths, lumber mills and more!

Customize

Upgrade your kingdom the way you want to, fine-tuning your playstyle! Most buildings have different upgrade paths, and your choices matter.

Factions

Do you prefer Norman longbow superiority, heavily armored Saxon Knights, or the Byzantine impenetrable walls? Every faction has unique units, buildings and playstyle.

Expand

Defeat bandits and brigands, claim their treasures and lands for your own!
