the badge where you have to kill all 300 spartans is very easy. all you need to do is:
1. Buy The Quaker gun
2. fully upgrade it
3. fully upgrade wall
4. buy 3 Flamer Joe towers
5. upgrade each tower's damage 2 points
6. CLICK LIKE MADNESS UNTIL IT'S OVER!
by doing this i finished the mini game with 575/600 health and i didn't even have to repair the tower once.
lol i love hearing people go like "ugh i'm stuck on lvl 14" hahaha. on level 21 i remember dying like 300 times. now that i've beat level 50, i tried it again WITHOUT dying. you guys are screwed if you are stuck before level 40!
omg if you have any mercy towards your fingers you will NOT do My Heart Up Your Ass on pro. omg my fingers are numb and my face is sweaty right now, jeez.
