i beat the level 36 boss with big laser lightning and shortshield, when he isnt attacking just use all three, and randomly attack with big laser trying to hit him, takes a while to learn his patterns but eh
I got exactly 300 spartans. The best tactic is to upgrade the quaker fully, then buy as much gunners as you can. Credit to escrimadragon for giving me that tactic
I tried 12 once, failed, then i tried again when i realized you could select more then one cell...it became easy as, but its a great game i really like it. got up to 1k cells in the last level
