Apparently an Aquaman video game is in the works as an image has surfaced online from "Eipix Con" back in December.
The Aquaman video game, which appears to be a mobile game, is from Eipix Entertainment, an independent game developer known for various mobile games including Spiny Core, Nom Nom, Hoppy Land, Free The Witch, Vermillion Watch and more.
Cosmic Book News has reached out to Eipix Entertainment for further information and is presently awaiting a reply.
Update: Eipix Entertainment got back to us and stated the Aquaman concept art is for a potential video game (read their response here).
Jason Momoa appears next as Aquaman in Zack Snyder's Justice League, out November 17, 2017, followed by the release of Aquaman on October 5, 2018.
