Okay so I absolutely love this game and playing just wish I hopped on late so I had a whole game to play.......well not not really it's fun this way. The shock towers don't seem to be doing much... At first I used them on the mix.r as defense. I could here the hit audio que..but then when I failed, needed to go back to my home base to get stuff to get stuff for builder purposes a generated orc bug was just sitting there not getting damaged. So with the 9 or so Towers I have I let it chase me around. No damage to it. Tested it with a scheduled attack. Same thing.
