Attendees are also going to get updates on Respawn's Titanfall. The team has already said that they are going to reveal a new game mode and new features where the attendees will be able to play and test at the event.
Titanfall had an overall successful launch, but there has been a push to try and make the game more competitive and long-lasting. Some players felt the game was monotonous and boring after a few hours so Respawn has been trying their best to change that.
They took away game modes in what was one of the first times I've seen a company do something of that nature. Capture the Flag and Pilot Hunter were taken down just two months after launch and later put as an option for private matches due to "lack of demand," according to EA.
