Austin Wintory, the composer for The Banner Saga, used adaptations of Norse proverbs and poetry, as well as lines from the game itself, as vocals for several songs in the game's soundtrack. The vocals were done in Icelandic, the closest language to replicating Old Norse.

Those who pre-ordered The Banner Saga or backed the game on Kickstarter received a special version of the game that gave them access to an exclusive party member; a Spearmaster named Tryggvi.
