The Banner Saga is a tactical turn-based RPG in a Norse-inspired fantasy setting with an art style influenced by traditional rotoscopic animation from the 50s-80s.
The multiplayer is a stand-alone free-to-play component of the main game called The Banner Saga: Factions. Currently, the multplayer consists of having two players against each other in turn-based combat with 6 characters from a pool of 16 classes. Players are able to customize the characters via stats and the like to suit their tactical play. In addition, there are additional powers and the like that can be obtained by in game micro-transactions, albeit players with these would be match-made with similar players.
Developed by a small team of former BioWare artists, this game was fan-funded using Kickstarter and received over 700% backer support, making it one of the most successful projects at the time.
The multiplayer component was released as a stand-alone game to allow the developers to hone the basic gameplay mechanics based on player feedback, as well as continue to fund the game.
