Banner Saga: Factions — allows players to pit teams of six fighters, chosen from 16 classes, against each other on a grid. Players have their units perform actions, such as moving or attacking, alternately. All units can be renamed by the player. The player can also purchase new characters from the Mead House building or upgrade their stats using an in-game currency called "Glory", which can be earned through matches or purchased through microtransactions. There are four base classes, each of which can be upgraded to three different classes. Renown can also be used to expand barracks, allowing the player to increase the maximum number of units they can have.
