As someone who has been slightly obsessed over the Vikings series from the History network, a game based around Norse mythology is exactly what I need right now.
Viking Vengeance from Lowpoly Interactive is due out sometime later this year and it is currently advertising Linux support on Steam. When speaking to the developer about it in this forum post, they said "Hello and thank you for the question. Yes if people using Linux will be interested in the game we will definitely bring it to Linux.", so it might be worth letting them know if you're interested.
Early gameplay trailer:
- From Midgard to Valhalla and Asgard you will encounter a variety of worlds, legends and characters. You will write your own destiny and follow your path to vengeance and immortality.
- Earn the gods favors by doing a variety of activities, from fixing their idol statues and praying to summon them or their powers in battle.
- The game will offer over 20 hours of gameplay with different locations, different quests, different foes and different equipment and skills to unlock from the gods.
- Unique combat system including the ability to push enemies off cliffs, drowning, executing enemies, using traps and environment or wild animals in your favor.
