Sons Of Tyr is a multi-player RPG in a Viking world. Create your character and follow the tutorial to equip you with necessary beginner weapons and armor. Then explore your Viking island hub where you can upgrade NCP areas to purchase new weapons, armor and gear.
Then head out on a boat, kill bandits and loot nearby islands. There are animals and even giants roaming around the islands.
The current version is free on itch.io and ran well in Wine. I did experience a problem playing multi-player on a LAN. When I hosted the game and we traveled to an island my character would reset and loose all inventory items. Otherwise, playing single-player was a lot of fun.
