Don't know of any walkthroughs that are still out there. The one I knew of is gone.
This chart of progressions is posted in several places. Can't remember where the roiginal post is: http://www.geocities.com/ivdtac/Images/god_progression.jpg
Chart is wrong.. Dont need smith rondo etc for KT access any more.. You only need Tipt. Also Txevu should be grey, not pink since there are 3 targets that needs to die before you can enter Tacvi.
