This is a quite a pretty straight forward type of mission, or in other words, an easy one. The main objective is to defeat an enemy by means of destroying the object that they are standing on. This guide will thoroughly explain to you on how to accomplish this task.

Here are the steps you need to follow:

1. First thing to do is to locate the area for destruction. Run all the way forward.

2. Once you reach an intersection, head towards your left.

3. There you will get blasted with some missiles. An indication of the enemy.
Hint: The enemy is located on top of the balcony you see.

4. Throw a number of Alpha Grenades up the balcony.

5. A few seconds later, a message will appear that you’ve earned the Watch That First Step Trophy.
