For somewhere in the region of four quid you'll be able to pick up Warhawk DLC/expansion Omega Dawn this month, and here's 10 screenshots from the content update.
Omega Dawn includes five new maps and one new vehicle - the KT-424 Combat Dropship, which can hold seven soldiers, a pilot and a vehicle. Plus, there's a rather meaty cannon on the top of it, so you can already tell it's going to shake up existing maps and game modes quite significantly.
Sony's said the new maps will support all game modes and you can use Omega Dawn's new Dropship on all existing levels. And if you haven't already check out the review for the original game.
