Today Respawn Entertainment got their website up and running. They also decide it was a good idea to tease what they are working on as part of the publishing deal they have with EA. As you can see in the photo below, it isn't much to go off of but it does show they are getting shit done.
Respawn Entertainment is the brain child of Jason West and Vince Zampella, former heads of Infinity Ward until they were fired by Activision. These guys managed to pull over 30 employees from Infinity Ward to come join them over at Respawn. Its amazing that they have a game fully into production with this huge lawsuit between them and Activision.
