Over two months ago we encouraged you to go and sign up for the open public beta of http://www.trueachievements.com/Gotham-City-Impostors-x....htm
. Apparently the limited codes have failed to run out, because Warner Bros. Interactive Entertainment is still encouraging people to sign up even on the day that the beta launches on the Xbox 360. The beta can only be downloaded by those gamers who hold a beta key. To sign up for a key, visit the game website
Have a look at the new "Simple Math" trailer that was released to celebrate today's launch of the beta:Gotham City Impostors
