Transformers: Fall of Cybertron receives its first DLC today, including the previously announced and detailed "Dinobot Destructor Pack." In addition to that, Activision also put out the "Multiplayer Havok Pack" today.
The Dinobot bundle is probably what most Fall of Cybertron fans are looking at though. The add-on basically unlocks customizations from four Dinobots -- the ones seen in-game -- for multiplayer use, whether you want the whole kit or just bits and pieces.
Havoc Pack, on the other hand, includes the full bodies/parts of Ultra Magnus, Wheeljack, Blast Off, Zeta Prime, and Perceptor.
If that's not enough, a "Massive Fury Pack" is due September 25, introducing both multiplayer and single-player content. For multiplayer, this will add Insecticon customizations, G1 Optimus, and Autobot Hound. In single-player, you'll have access to the G2 Bruticus skin, G1 Shockwave Blast Cannon and G1 Megatron Pistol Gun weapons. Some of this stuff was previously pre-order content.
All packs are priced individually at 800 Microsoft Points or $9.99, depending on what you're playing on.
