Set upon an extended map of the British Isles and western Scandinavia and taking place from 793 to 1066, Viking Invasion allows the player to assume the role of leader of the Viking faction as they raid, loot and pillage their way to supremacy.
Alternatively the player may take control of early Anglo-Saxon factions, such as Wessex and Mercia, with the aim of repelling the Viking invasion and ultimately controlling the British Isles in its entirety.

• Adds new Anglo-Saxon and Viking factions with additional units alongside the detailed new Campaign map.
• Also includes added functionality for the main game, such as flaming ammunition and three new factions with which to play through the original Grand Campaign.
