Boss Rush

Every game has a Boss Rush mode, so why not BTD?! In this new mode, you're given 10000$ cash to start, and you're given a HUGE sum of money after each round! You must fight a series of bosses here, one for each round. If you complete this mode, you'll get a Platinum medal for that track. You must get the gold medal for a track first before you can play Boss Rush on that track.
