This one had me kinda ticked too, put it on the ground in the middle of the U of the base(not very clearly worded, but I think you'll understand what I'm saying).
I was kind of irritated after I placed over a dozen bombs inside the freakin base and that didn't work, then I just popped one down on the "lawn" quite a distance from the actual building and boom!
You are just about to the Sea Nymph now, very different play type then the Meccs(she moves fuggin fast, particularly with her turbo🙂). Have you ahh, fixed the censorship yet? If not move or delete-
C:\Program Files\Giants\Bin\arpfix.gzp
That will take the top off of the Nymph(is that what she is called, I'm forgetting now). There is also a patch to turn the blood red at Planet Moon's website(at least, that is where I got it).
