Hawkeye Achievement - seems to not work. I have tried 4 towers with only falconer and 4 towers with Barrage and only 1 falconer. Neither seems to work.
Maybe it's me, but I would like to see a scaled listing of the colors of equipment and a floating compare box, so I can actually see the equipment being compared.
 "Kingdom Rush Frontiers"){kind=icon}
 "Sands of the Coliseum"){kind=icon}
