Matt Piersall

Matt Piersall is a sound designer and the president and audio director of GL33k, an audio design company based in Texas. In 2004, Piersall was contracted as a sound support designer for Metroid Prime 2: Echoes, where he "provided sound design and on-site integration at Retro Studios". Following this, Piersall worked on Metroid Prime 3: Corruption with greater involvement. Piersall enjoyed working on Corruption with audio lead Scott Petersen. According to GL33k's website, they used a Kyma, a hardware-driven sound design system to create creature sound effects. Their main focus was on creature, user interface and world sounds.

According to Piersall, "one of the biggest undertakings" was Samus's Aran's Gunship. Sounds for the gunship were assembled from Petersen's stove, "Kyma'd whales, simple FM synthesis, and many sample-based Absynth patches". The team completed around 30 scenes involving Samus's ship.

Piersall features the Reptilicus, Gragnol, Hoppers (mistakenly identified as Fargul), Nightbarbs and Shelbugs (spelled Shell Bug) in a Creature Demo reel on Vimeo, showcasing creatures and their sounds in games GL33k has worked on. The video is linked below; Reptilicus starts at 3:00, Gragnol at 4:00, Hoppers at 4:26, Nightbarbs at 5:04 and Shelbugs at 5:32.
