According to the reveal trailer and the developer's website, SMITE Tactics will be a turn-based strategy game that takes place in the same universe as SMITE and will feature many of the same gods and goddesses from the MOBA. Some of the deities already seen in the trailer include Ymir, Zeus, Odin, and Aphrodite.
Gameplay footage from the trailer shows a combination of traditional card-playing with a grid-based tactical battle system. The website states that "Every unit has unique abilities and players will build their armies prior to battle using collectible cards. Players will be able to compete for prestige in 1v1 ranked competitive modes and experience various adventure modes versus AI."
No official word was given on when the final product will come out, but the closed beta for SMITE Tactics is scheduled to begin by the end of 2016. Would-be players can sign up to be a part of that beta here.
