Good mode to have. Enjoy the official details below.
Dynasty mode brings a brand-new free game mode to Total War: THREE KINGDOMS, designed in collaboration with Intel®. This new horde-style mode allows players to test their survival prowess against waves of enemies with ever-increasing difficulty levels using an army comprised solely of three hero units.
Characters in Dynasty mode are legendarily powerful and have access to a plethora of unique abilities, from healing buffs to area-based attacks which can floor droves of soldiers at a stroke. As your enemies fall to the might of your heroes, they grow in strength and size over time with generals taking to the field of battle every third wave in an attempt to halt your dominance. Defeating them earns your heroes extra points to spend on new skills between waves.
Players can also increase the challenge using the new unit size slider which enables players to drastically increase the unit size of the enemies they face from the standard 80 men up to a gargantuan 960 men per unit. This will test both their heroes’ skills – and their PCs’ performance – to the max!
Will you and your dynasty survive the forthcoming tide?
