A battle against “the boss” is often an important element of adventure video games. The boss is often portrayed as a supremely powerful, aggressive, scary monstrosity. As the game player, your job is to kill it. In some games, you battle against it alone, while in other games you are a member of a group that must use teamwork to take the boss down.
Here are two examples of music styles that work with a boss battle. The first style is electronic, and the second is a hybrid electronic / orchestral arrangement. In both styles, a driving percussion rhythm and strong bass pattern accompany the action.
