During the #BE3 Conference more Elder Scrolls: Legends information was released, ESL is a collectible card game which revolves around turn-based matches between two opponents. The cards are based off creatures, characters and lore found in The Elder Scrolls series.
At the start of every battle, each player starts off with three cards and one magicka, which is used to deploy cards. When deploying these cards, the player can place them on one of two sides, called lanes. Lanes can have special abilities which alter the fields of battle. A card in one lane can either attack another card in that lane, or attack their opponent directly. If either of the two players take enough damage, one of their runes will shatter. When this occurs, the same player will immediately deploy a card. The game consists of five game modes, which are a story mode, solo arena, versus battle, practice mode and a versus arena.
