Our friendly neighborhood sorrontis made a map with 5 of those cannons, every one of them beign huge power hogs. Would be nice to be able to turn them off (activate/deactivate), so I could actually build a ship or two ;)
Yeah, that's on my list. It's a tad tricky since they can flip sides (and if they do, the enemy will turn it back on), but I'll be adding it soon.
