Shock and Awe!

 is an achievement in the Bloons TD 4 app awarded for destroying a M.O.A.B within 1 second of it spawning. To achieve it, you must place your towers in a place where they can hit the beginning of the track. You are more likely to earn this on a later round; it is worth 50 achievement points.

Trivia

 * The name of Bloons Tower Defense 5's Pop and Awe Ability may have come from this achievement.
 * An easy way to get it is to spam M.O.A.B. Maulers at the beginning of a track, and set their Target Priority to 'strong'.
