Sledgehammer Games was founded during summer 2009 by Glen Schofield and Michael Condrey and acquired by Activision the same year. The studio originally worked on Call of Duty: Vietnam, a third-person shooter set during the Cold War.
In early 2011, following tensions between Activision and Infinity Ward, leading to the departure of its founders and half of its staff, Sledgehammer Games was tasked to assist the remaining staff of Infinity Ward on what would become Call of Duty: Modern Warfare 3. Call of Duty: Vietnam was put on hiatus and subsequently cancelled. Modern Warfare 3 was a massive success grossing over $400 million on its launch day and became the fastest-grossing entertainement product to reach $1 billion in 16 days. The record was eventually broken by Call of Duty: Black Ops II when it reached $1 billion in 15 days.
After Modern Warfare 3, Sledgehammer Games became one of the primary studios with Infinity Ward and Treyarch, creating a 3-years release cycle, and developed Call of Duty: Advanced Warfare released in 2014. Advanced Warfare was created using a re-written custom in-house engine based on the IW engine and featured Exo Movements for the first time in the franchise.
In 2017, Sledgehammer Games released Call of Duty: WWII, the first Call of Duty game set during World War II since Call of Duty: World at War in 2008. WWII used the same engine as Advanced Warfare. WWII grossed over $500 million within its first three days of release and crossed $1 billion the following month.
On February 20, 2018, Glen Schofield and Michael Condrey left the studio and were promoted to executive duties at Activision before leaving the company the following months.
