Rise of the Triad video review & walkthrough
 

Recently I've stumbled upon an impressive collection of video walkthroughs for all levels of Rise of the Triad (shareware episode and Extreme Rise of the Triad included, plus a few extras):

All videos are supplied with interesting and witty comments, listening to which makes a great entertainment in itself, apart from the walkthroughs that are rather detailed and in most cases cover all of the secret areas within a particular level. These videos are probably the number one source of in-depth information about the game alongside with the official FAQ. Apparently, the guy who did these videos is a prominent member of Something Awful.

As an undeniable confirmation of quality of this video collection, Joe Siegler himself gave it his delighted approval.

Another thing definitely worth watching too is this video review of the game, which is part of the Era Game Reviews (a pretty nice series of reviews of old games, by the way):
