Here's a funny little thing. I played through the entire game, and decided to start a new playthrough where I would take it more slow and primarily play with an Xbox controller to replicate what the game is like on Xbox just for fun.

Anyways, it suddenly struck me that I had added the Sewers DLC key to Steam for pre-ordering the game, but I had never EVER been in a sewer in the entire game, and I don't think I'm the only one.

I only just found out now what the actual DLC is, and I'd recommend you check it out too:

http://rage.wikia.com/wiki/Wasteland_Sewer_Missions_(DLC)

The sewers are:

• Ark Area Sewers
  
• Outrigger Sewers
  
• Southern Sewers
  
• Wellspring Sewers
  
• Northern Sewers
  
• Kvasir's Sewers
  
• Plateau Sewers

geez come on mate , get with the program you've been asleep in the ark to long , welcome to the future .

There are 9 of em that I missed on my first playthrough

I watch the 2nd mission on YouTube and it had a good length to it

So that's more shooting baddies on the 2nd playthrough plus hopefully the 2nd DLC is out by that time as well

yea xaxxiron777, you are missing two of them, those you listed are in the Wastelands / Wellspring -- the last two are in Eastern Wastelands/Subway City

One is right outside subway city, the other in the shipyard area


Also note that once you have completed each of these, a new job appears on the job board to go back and clean them - thats 18 sub missions.

yeah also saw that on the Wikipage for RAGE (hey that rhymes! ) but didn't bother to update op

Personally I found it insulting that a game which is already over 20GB in file size, reuses many maps, and has too short a beginning and ending, would not have such files already included in the stock game. They not only shouldn't be charging extra for it, it's a whopping 11.7GB download!

Personally, I loved the map reuse thing with minor details changed. That added a lot to an otherwise linear game and didn't seem repetitive at all :]
