In a Counter-Strike map, there are two kinds of sounds. There are the ambient soundsources, that always give sound, and there are sounds that are activated by triggers. These can be important, because they may help you to find your enemies, especially in a 1v1 situation. On aztec you may realize that it is often thundering. These thunders are activated by different triggers. There are triggers at:
- under the T archway
- in the middle of the bridge
- int he middle of the CT stairs
- under CT archway
If someone walks over a trigger, it is activated. It is mostly used while defending the bridge, becouse you dont have to look out, you may know the enemy is there.
