You can download the text version of this walkthrough here. It's slightly different from the online version. For example, it doesn't have the screenshots and links to NSMs. However, you don't need to be online to view it.
NOTE: This may not download automatically. If this is so, you can do one of two things. First, you can open the files in your browser, then go to File>Save As. Or, you can right-click the link and select Save Target As. If it doesn't work, e-mail me, titling your email "Bionic Commando" or something similar so I won't think it's spam and delete it.
