DocDave: How do you turn off the water fall to get to the secret room? The walkthrough on Planet Adelpha says: "Remember that Kyuran didn't know why that place north of the waterfall
was on the map? Head there. You'll see a great big boulder with two
smaller rocks in front of it. Using one of your first two guns (first-
person mode helps here), you'll need to get the two small rocks banging
against the huge one _in unison_ with enough force to dislodge it. Of
course, once you dislodge it, it's a good idea to get out of the way."
I can't seem to find the boulder. :(
IIRC, it's kind of north of the old Guardian Training camp (the place that looks like a huge fortress of stone) and kind of east of that big pit where the giant snake-monster is. All that is on the opposite side of the bridge from the doaka you come out of. It should be visible on your tactical mini-map and your Shamaz-given map.
