Just remember, if you beat a mode, you only get the amount you would get replaced with like 300,200,and 100, BUT IF YOU LOSE, YOU GET THE REWARD, SO DOING DESERT ON THE HARDEST MODE (Not Endless) AND THEN LOSING ON WAVE 2, YOU GET 32K COINS!!!!
tip for beating extreme (start with large speaker tv man and bring any one of acid gunner utc/astro utc and any money maker (besides engineer i recommend bringing scientist cam and after u get enough money to place titan sell large speaker tv and place the titan and place a money maker and max it out (wich will take about 8-10 waves depending on ur timing) (then after that spam the titans)
uuhhh bemmy only reason why the nugget didnt attack at wave 20 because the nugget cant not attack flying enemys (edit even tho that some people know that already
