Pick up the crowbar of research scientist Gordon Freeman, who finds himself on an alien-infested Earth being picked to the bone, its resources depleted, its populace dwindling. Freeman is thrust into the unenviable role of rescuing the world from the wrong he unleashed back at Black Mesa. And a lot of people, people he cares about, are counting on him.
You control a musical avatar who must battle for control of the airwaves. Notes are your resources, and by playing them in time with the music you can summon units, build an army, and conquer the opposing musical faction.
Dissonance combines the gameplay of a real time strategy game with that of a rhythm game to bring players a completely new experience. After selecting a faction (Metal or Techno), the player is dropped into the world where they are placed in control of a musical avatar. Using this avatar, the player can capture towers, which in turn provide a steady stream of note resources. The player can play these notes at any time to summon units and upgrade towers. Ultimately, the game is won by capturing the stage and playing the concert: a long and difficult note sequence.
