GHETTO BLASTER BLASTER Achievement
To get this achievement you need to destroy all four radios in the game. Pretty much all radios are easy to find and play a loud music.
In chapter 2 you can easily find two radios.
At the end of the chapter you find another radio in room with two soldiers next to two soda machines.
The last radio is in chapter 3 and is probably the only radio that you could miss. In the North Entrance there is a vent entrance on the floor. Get inside to find the last radio in a corridor.
