The spy-thriller, Spyder , from studio Sumo Digital, is an homage to a classic genre that had its golden age in the 1960s. The Apple Arcade game features an adorable mechanical spider, Agent 8, created like one of James Bond's gadgets, that players control during missions that are increasingly dangerous. Composer Winifred Phillips created the perfect '60s and early '70s inspired soundtrack, featuring elements of jazz, orchestral, and even early synth rock sounds. She says doing the research by reviewing classic spy and adventure films and TV shows helped her keep the score pitch-perfect. Winifred says the first music she wrote for Spyder was the trailer soundtrack, which encapsulates lots of aspects of the game: suspense, heroics, and Agent 8's confident swagger. Winifred's insightful articles about writing game soundtracks appear regularly on Gamasutra, and her sessions at the annual Game Developers Conference are among the most well-attended. She was planning to present a session
