SOLUTION FREE! :D  
  
the highlight is of course the explosion technique. if i recall correctly, this cso trick hadn't been in this series yet.  
it works as follows (o = empty space):  
  
ooΖΒΔ  
oΚΓΔΔ  
ΔΔΔΔΔ  
  
that's basically the starting point. the Ζ is now scanned first. it checks if it "sees" Κ beside it which is not the case, so it does not explode. instead, it moves left, Κ is scanned afterwards and escapes to the right.  
  
oΖoΒΔ  
ooΚΔΔ  
ΔΔΔΔΔ  
  
again the Ζ is scanned first. it still cannot "see" Κ, so it moves down. Κ escapes upwards.  
  
ooΚΒΔ  
oΖoΔΔ  
ΔΔΔΔΔ  
  
this time, Κ is scanned first, and he moves up (out of my 5x3 rectangle, in fact.) note that Κ must n o t move left instead, then the Ζ would see him and explode!   
after Κ has moved up, the Β comes into play. it has enough free space to fall sideways now and change into "falling Β". the Ζ is scanned last, it moves right.  
  
ooΒoΔ  
ooΖΔΔ  
ΔΔΔΔΔ  
  
that's it! Β and Ζ are in position, and the Β now crushes the Ζ!  
  
the other cso effect in the cave is a rather standard one - it's the way how Κ passes the top-mid ΒΒΒ to move from the right half into the left half. this method could not be mirrored.
