I picked up the "Call Of Duty: Black Ops" book yesterday at Wal-Mart (US List Price - 19.99 but I got it a few bucks cheaper - it's Wal-Mart).

It's full of charts, maps, hint's, tips, etc, all in full color.  This is an "offical" book done with Treyarchs approval and help - well worth the money.

Most command references are for the console versions, but you should be able to figure them out.

NOTE:  on page 158, The Secrets, GETTING OUT OF THE CHAIR - the book says to alternate the
Fire and Alternate Fire buttons, but on the PC, just hit the spacebar repeatedly till you stand up.

Thanks for the great info AGS!
