Details of a new hero shooter in development at Valve, known as Deadlock, have been leaked online. Once known for releasing critically acclaimed titles like Half-Life, Portal, and Left 4 Dead, recent years have seen Valve focus primarily on Steam. The company also released Counter-Strike 2 last year, which replaced its predecessor, Counter-Strike: Global Offensive. Despite this, Valve fans have continued to wonder when the renowned gaming company will release its next big title.
