Investigating Audio Production and Technology:
Exercise 1:

Game: God of War 3
Sound: Thunder / Lightning
These sound effects convey a sense of danger, which also symbolises what is coming as this kind of weather and sound effects occur in the game moments before something big happens, e.g boss fight or important scene.

Game: Outlast 2
Sound: Panting / Heavy breathing
This sound effect symbolises exhaustion to the player, after sprinting for a certain amount of time the character will lose stamina and become more tired, the heavy breathing and panting tells the player that they are becoming tired and will need to stop sprinting soon.

Game: Overwatch
Sound: Endgame music
As the current game the player is in approaches finish, for the last 30 seconds or so the music will pick up and become more intense / dramatic. This conveys that time is running out and both teams have one final attempt to win the match, it overall symbolizes the end of the game.
