In the world of sync, Cinetools is one of the best. Their top-notch quality always shines in their productions. This isn't a huge set, but it gives you great stuff to work with. These are great 'emphasizers' / 'stingers' which are made up of orchestral hits to strengthen a peak of something. These sounds build tension and work amazingly to accentuate a particular section of a scene. Definitely layer these sounds up and use dark, moody pads and beds surrounding them for full effect.
