Tried this out and I like the idea but there is one huge issue. It kills your UPS, dropped mine from 60 to 30. Even without placing on on the map it kills your UPS. Once I disabled the mod my UPS went back up to 60.

I'm guessing it's the range but if it's not placed on map it should not be doing anything. The map I am playing on has a ton of territory unmasked from exploring so you can see a really long ways in map view. It may not lag on a new game or one where most of the map is hidden, did not try that.

Also it would be good if the map pings were optional in settings, they can get annoying once a lot of map is unmasked.

I did not see it kill any biters, I drew some in with artillery strikes to see what it did. Is it suppose to also kill ?

I confirm, when the mod is turned on, there is a strong drawdown, which indicates that incorrect data has crept into the code somewhere.
I have not tried playing with this tower, since it is uncomfortable to play with such lags.
I hope the author will figure it out and fix the code.
