From the website:
After years of tireless explorations, brave Vikings have discovered a new land filled with mystery, danger and riches: Northgard.
The boldest Northmen have set sail to explore and conquer these new shores, bring fame to their Clan and write history through conquest, trading, or devotion to the Gods.
That is, if they can survive the dire wolves and undead warriors roaming the land, befriend or defeat the giants, and survive the harshest winters ever witnessed in the North.
Build your settlement on the newly discovered continent of Northgard
Assign your vikings to various jobs (Farmer, Warrior, Sailor, Loremaster…)
Manage your resources carefully and survive harsh winters and vicious foes
Expand and discover new territory with unique strategic opportunities
Achieve different victory conditions (Conquest, Fame, Lore, Trading…)
Play against an AI with different difficulty levels and personalities
Enjoy dedicated servers and grind the ranks to reach the final Norse God rank!
After each additional clan release, Northgard is upgraded by free major content which add new ways to play, and allow you to discover all the possibilities that Northgard offers you.
The map you’ll be playing on when choosing Ragnarok is completely devastated. Your path towards your opponents may be guarded by dangerous creatures! The center of the map is occupied by a new special tile: the Volcano
The knowledge of building Relics has just been rediscovered. Every clan can choose between 5 common Relics and each clan has one specific relic. Each clan can only have one relic per game and can only use the relic it creates.
Northgard Conquest is a standalone game-mode that can be played solo or co-op, with a succession of various challenges offering a gaming expansion of +100 hours. The difficulty of the co-op mode will be based on strong collaboration between players.
