Formal (Matthew Piper) — Call of Duty Professional Player Settings and Gear
About Formal
Matthew 'Formal' Piper is one of the most naturally talented players in Call of Duty history and the AR slayer on the legendary OpTic dynasty roster that defined competitive CoD. Before dominating Call of Duty, Formal was a professional Halo player — and not just any Halo player, but one of the best in the world, making his cross-game transition one of the most successful in console esports history. His arrival in CoD was immediately impactful, and his signing to OpTic Gaming in 2015 created the dynasty roster alongside Scump, Crimsix, and Karma that would go on to win the 2017 CWL Championship and dominate the competitive landscape for years. Formal's gunplay is what separates him from other AR players — his ability to lock onto targets with seemingly zero effort earned him the reputation of having the best centering in CoD history. His sniper play was equally devastating, with Formal regularly pulling out snipers in situations where no other AR player would dare, hitting shots that left opponents and spectators in disbelief. The combination of his Halo background — which gave him extraordinary spatial awareness and movement mechanics on a controller — with his natural CoD talent made Formal a unique hybrid player that nobody could replicate. His mouse settings for PC gaming reflect the same precision-first approach, with a moderate sensitivity that mirrors his deliberate, accuracy-focused playstyle from competitive controller play.
