Once again the Bloons Tower Defense game fails to take responsibility for the United Fruit Company's atrocities in Guatemala. I am sorely disappointed.
Hard badge: Get all upgrades except the slow/poison towers. For the first 1/4-1/3 of the waves aggressively "send now" while building supertowers. Then send the rest all at once and start up your bomb spamming macro, or use "z" if you don't know about macros.
This game changed my life. After playing it I cried for 3 days straight then quit my job and joined the Peace Corps. I told my girlfriend to keep the baby because all life is precious. My father was diagnosed with terminal cancer but when he played this game he recovered.
