Omega Dawn is the first expansion pack to be released for the game. It features a new vehicle, the Dropship, and a new map, Omega Factory. Descriptions of Omega Dawn, along with relevant screenshots, can be found here and here at Sony's playstation.com blog. Here's a copy of some of that blog info:
The Omega Dawn Booster pack adds 3 key things:
- A night-time battlefield with 6 layouts called the “Omega Factory”. It’s huge btw.
* New 7-player aircraft called the KT-424 Combat Dropship.
* And 5 updated bonus layouts for battlefields from the original game so that you can play using the new Dropship.
