This is really pretty easy once you have gotten the right locations down. Just suit up and take your wads of useless cash with you.

Some things you might note:

• You're going to need plenty of cash with you if you want to survive the lack of oxygen on the moon.
  
• You must be somewhere where there is a medic vendor out of the range of Oz (or O2)
  
• Get ready to sit for 5 mins twiddling your thumbs cus that's what you're in for.

Ok, so one of the best places to do this is the Outlands Canyon. (Also I did it here)

Once you're there go to where Pickle is located.

There is an Air Dome Generator on a platform near Pickle.

Here's the tricky part: you need to turn it off. Ya hear? O-F-F

(Also you may want to take off your Oz Kit)

Go down to the lower part of Pickle's campment and there will be a health vendor.

You can start anytime, but it helps if you start the time somewhere close to the Daily Deal timer.

After that, you can (recomended) buy health everytime your health goes down 25% or lower.

Once 5 mins are up you got another spiffy achievement to put on your wall for all to see.
(Note: If there are other places that you can do this please share them since this is only one location and does not apply to everyone.)

This has been my first time making a guide, so complaints and/or issues will be accepted (but will probally see the incinerator).

Seriously, any questions? If you do leave a comment in the comments below and I will help (or someone else will).
