There is new downloadable content for Transformers: Fall of Cybertron available right now. The Massive Fury Pack includes new multiplayer characters along with adding their bodies and individual parts to the multiplayer character creator (which was my favorite part of Transformers: Fall of Cybertron).
The new characters are the Insecticons Kickback, Sharpshot, and Hardshell, G1 Retro Optimus Prime and the Autobot Hound. Three new singleplayer items are included. You'll get the G2 Bruticus character skin, along with two new weapons: the G1 Shockwave Blast Cannon, and the G1 Megatron Pistol Gun.
