I'm glad to announce that I have finished my second Herzog Zwei Strategy Guide. It's now available at my website.
This guide is larger than the first, and deals with a lot of specific situations and tactics. Strategies for each of the game's 8 stages, defense, offense, using your Mech effectively, convoys, supply truck formations, beating the computer...everything I could think of.
Herzog Zwei is a personal favorite of mine, and I wanted a definitive source that fans could turn to (learning the game is a pain w/o an instruction book). I hope you all enjoy it.
My best bit of advice:
"Don't make the 'Transformers' sound when your Mech changes. Nobody likes a dweeb."
