Sound effects

From feedback my audience suggested to put sound effects on my trailer as at the moment it only looks like a horror film not a horror and sci-fi.

Research into sci-fi sound effects





After looking at examples of sound effects I have made a list of sounds I want for my trailer, this will help me get all the effects I need quickly. I will be getting the effects from free sounds as they have lost of sounds I can choose from and they are good quality. Hopefully the sound effects will create a more sci-fi atmosphere with hints of horror.

Sound effects I need:
Foot steps
Heavy breathing
Sci-fi sounds
Alien sounds
Ufo sounds
Screaming
Crying
Gasp
Wood or sci-fi atmosphere
Tv
Door
