153 sound effect loops for abstract or Sci-Fi games, devided into atmospheres, high frequencies, low frequencies, rhythms, risers and voices. Each can be perfectly used on it´s own. As well, it´s possible to layer them to make them even more complex, accordingly to the situation in the game. Any loops from different categories will sound well together. This way the sound could get more and more intense. Individual background sound constructs can be easily created with this pack.
