Here a few barriers surrounding me in the TexDex quest. I played this for over seven hours (subscreen time).
#1: I cannot find Level 5 in the TexDex Quest. I used bombs everywhere, and there is a place inside the big cave that won't make go down the ladder. I tried looking everywhere. I skipped this level and went on to Levels 6 and 7. Where is it?
#2: I cannot find the Letter. Again, I looked everywhere, but there was no signs of the Letter.
Alucard will take the exact location of the answers of these missing pieces of the puzzle to the TexDex Quest.
