Sunset Overdrive DLC released to coincide with price drop

The hilariously titled Dawn of the Rise of the Fallen Machines has dropped, along with the price of Sunset Overdrive, which is now going for $39.99 in the US. Insomniac's website describes the DLC like so:

The savage battle that’s been raging on for billions of years enters its latest bout in Dawn of the Rise of the Fallen Machines. A rescue mission to save Sam’s old mentors from the Fizzco Robotics Factory quickly turns into an all-out assault to counter-hack and dismantle Fizzco defenses. Don’t worry. For you, hacking equates to pulling triggers and laying waste to a bevy of upgraded Fizzco bots. Everyone has their strengths!

In addition, there is a new area to explore, and new weapons, enemies, outfits and other things to go along with it. There is a new achievement, worth 200 freakin' gamerscore, for replaying and completing the “Floating Garbage” mission within par time, 15 minutes. It seems like a lot of content for only $9.99, but it's included in the season pass, so keep that in mind before you buy it.
