So, spoiler-time for anyone who's not been following E3 coverage, but the Gorn will apparently now be the villains in the game. Personally, I'm all for this - despite having only appeared in one episode each of two different Trek shows (three if you count the Animated Series), the Gorn were always portrayed as a major spacefaring power, yet we've never been afforded a significant look at their culture. There've been a very few comics and novels (Typhon Pact: Seize the Fire, Alien Spotlight: Gorn, and TNG: The Gorn Crisis) that focused on the Gorn, although they've given us our best looks thus far at a mostly mysterious race.
Only time will tell how closely the Gorn of the JJ-verse will match up with what we already know, although early indications seem to point to "not very much", based on this quote from the most recent press release for the game - "a true military dictatorship, [...] made up of billions of self-sacrificing warriors across thousands of colonies, each focused on the conquest of alien races. By utilizing their chaos-causing infectious venom, the Gorn seed mayhem and destruction as they destroy populations and deplete planets of their resources."
Additionally, its been revealed that there will be a minimum of three "classes" of Gorn players will face in the game - Rushers, Warriors, and Brutes, and that the females of the species will be able to climb walls. The "chaos-causing infectious venom" will also likely be a featured gameplay mechanic.
The visual look of the Gorn seems to be (from the single screenshot we have thus far - hopefully by the end of E3, we'll get a better look) in line with the heavily-altered Gorn cut out of the 09 film (Picture).
More on this as it becomes available.
