Simon Viklund is a composer, sound director, and game designer at Stockholm-based game developer GRIN. Born to a family of multi-instrumentalists, he learnt piano and violin for a brief period in high school. However, he found his talent was creating electronic music when he received a copy of the tracker program FastTracker II from a friend. Around the same time, he enjoyed playing video games such as Bionic Commando  for the NES. At art high school, he met Ulf Andersson who went on to found GRIN with his brother in 1997. In the company's early years, Viklund was asked to score prototype games they created to gain funding from investment companies.

Viklund's first released project was handling all aspects of audio on 2001's futuristic racing title Ballistic. His pumping beats and riffs suited the notoriously fast gameplay and futuristic settings. He took a similar role on Bandits: Phoenix Rising blending techno, rock, and funk to produce very atmospheric soundscapes. In 2006, he adopted the role of sound designer on the Tom Clancy's Ghost Recon: Advanced Warfighter titles while Tom Salta handled the composition. He still used a legitimate version of FastTracker II to implement most of these projects, but has since switched to using a Logic Pro sequencer and a Buzz tracker.

Since the Tom Clancy projects, Viklund has focused on reviving Capcom's Bionic Commando series. Given his love for the original, he was chosen as the creative director of Bionic Commando Rearmed and decided on the direction the game should take. Also the composer, he created the score mainly by creating electronic remixes of all the melodies of the original in homage to the game and old-school game music in general. As lead sound designer of the Bionic Commando sequel, he decided to created a symphonic cinematic score given he felt the original aspired to take this approach. The score is headed by Hollywood composer Jamie Christopherson but some of Viklund's prototypes will likely make the final cut.
