Well, I plan on creating a few guides in the next couple of months, currently Im working on Starcraft 2. I also hope to do a Call Of Duty: Black Ops walkthrough too! But that will be later!
So far I think my SC2 guide is looking pretty good, I used differn't strategies then explicit D, but I also used his on certain levels....take Zero Hour for example, I bunker in at the top with 5 bunkers, and a few missile turrets, all on hard difficulty, EXCEPT two missions... Cutthroat and Engine of Destruction. Why? Because when I try to complete those two missions on hard, brutal, or casual, the game gets really laggy for the first intro cutscene then the whole thing crashes, I know it will upset some people but everything has its flaws, and this is the only flaw I can find with Starcraft 2... other then the fact that I got my ass whooped in my first online match >_>
And obviously for Black Ops I will be doing that on veteran, I might do something for the nazi zombie thing, if they implemented that.
btw explicit D, in the mission "Havens Fall" it is much better to comeplete it with the "Wraith" because it can attack both air and ground units. :D
