Mario Sello Nuñez on SoundBetter

Video Game Composer & Sound Designer creating immersive, modern game soundtracks - trusted by studios behind Abiotic Factor, Doomsday Paradise, The House of Hamelin, Heredity and more.

I’m a Video Game Composer and Sound Designer with experience since 2017 creating original soundtracks and custom game audio for indie and mid-sized studios. My music and SFX appear in titles such as Abiotic Factor, An Amazing Wizard, Doomsday Paradise, Heredity, and several other released and upcoming games.

I specialize in game music production with a focus on atmosphere, emotion, and strong thematic identity. Whether you’re looking for a sci-fi soundtrack, dark ambient music, fantasy music, combat themes, boss music, electronic game scores, or hybrid orchestral tracks, I can help shape the sonic world of your project.

Services I offer:

- Custom video game soundtracks (loops, levels, biomes, cutscenes, menus, bosses)
- Original game music in electronic, cinematic, ambient, metal, hybrid orchestral and more
- Game sound design (SFX for abilities, UI, environments, enemies, and interactions)
- Adaptive/loop-ready tracks optimized for in-game implementation
- Professional communication and fast delivery

My goal is to create memorable game music that enhances gameplay, builds immersion, and strengthens the emotional impact of your story and world.
