Hey shawn. If you aren't finding your answers on this site another resource is a unity custom search here: http://www.google.com/cse/m?cx=002470491425767499270:iugs1ezlsfq&cref=&theme=DEFAULT

I do a lot of searching there and it can help you in finding out the basics.

Your questions seem general enough to warrent a little searching before being asked on this site.

I don't think there's a quick and dirty way to pause. You'll have to:

• Stop the Physics Engine
• Stop all animations
• Possibly apply some image effect, like blur or black and white
• Disable character control
• Turn off other game elements
• Stop Enemy AI/Animation

Then you have to provide the GUI to give the options for Save/Load features or saved games

Hope this helps

Quoting myself from another similar question: 'Making a Pause Menu'

UnifyCommunity has a sample Pause Menu Script. There are also a bunch of informative answers in a question asking, 'How do I pause my game?'.

As for the saving/loading, take a look at 'How to script a Save/Load game option', or the Save and Load from XML sample (also at UnifyCommunity).

I found all these links by searching UnityAnswers for 'pause game' and 'saving loading' - you'll find a lot of questions have already been answered, just give it a search first!
