You're the Bomb Trophy in Prototype 2
You're the Bomb
10 or more kills using a single Bio-Bomb.
How to unlock You're the Bomb
You will automatically learn the Bio-Bomb ability during a main plot mission on the second island (Green Zone). It works best against infected people because they will run towards you in large hordes. You can find lots of them on the third island (Red Zone) and inside lairs. Grapple an enemy and press to activate the Bio-Bomb. Throw the enemy into a group of at least 10 persons.
