Matthew "FormaL" Piper is an American competitive Call of Duty player, formerly a competitive MLG Halo player. He currently plays for OpTic Gaming. FormaL has won tournaments in Halo: Reach, Halo 4, Halo 2 Anniversary, Call of Duty: Ghosts and Call of Duty: Advanced Warfare. He is the first (and only) competitive console FPS player to win an MLG event in both Halo and Call of Duty.

FormaL's breakout performance in competitive Halo was placing 5th at MLG Dallas 2011 together with Blaze, Brake and Areallygoodnoob on Team Soul. He continued to place top 8 throughout the 2011 MLG Pro Circuit, winning MLG Orlando 2011.

His competitive Call of Duty career began in 2014 with Call of Duty: Ghosts. Following a short period with teams Primal and FeaR, he joined Team Kaliber for the 2014 Call of Duty World Championship. With a disappointing elimination outside the Top 8, he immediately left the team to join the newly created FaZe Black, though never achieved anything aside from a Top 5 finish at UGC Niagara and MLG Anaheim.

In June of 2014, he joined EnVyUs and found immediate success on LAN by winning Gfinity G3, and setting the record for the first professional gamer to win a major LAN in both Halo and Call of Duty. FormaL and team EnVyUs continued to dominate for the rest of the Call of Duty: Ghosts season, taking 2nd place at UMG Dallas and winning Season 3 of the MLG Call of Duty: Ghosts League.

Following the release of the Halo Master Chief Collection, FormaL played with team Believe the Hype to win the Launch Invitational. He immediately returned to Call of Duty afterwards, joining OpTic Gaming.

OpTic FormaL and his team had a dominant start for the first few months of the Call of Duty: Advanced Warfare season, but suffered a disappointing 7th place finish at the 2015 Call of Duty Championship. As a result, Nadeshot – the captain of OpTic Gaming – announced his retirement from competitive Call of Duty. His team dominated LAN tournaments for the rest of the season.

Headed into Black Ops 3, Formal and his team would stick together. With Formal proving himself in Advanced Warfare, many saw him as the best AR in the game. Formal and his team would win 5 events heading into Call of Duty Championships 2016, where Optic would yet again fail, and place 7/8.

Going into Infinite Warfare, the team would stick together, and be the favorites for most events. Formal would then win 4 events, including the big one...Call of Duty Championships 2017, where Formal would win his first ring, and cement himself as the greatest AR ever, and a top 5 player ever. In 2017, FormaL would also win console player of the year at the esports industry awards.
