Overwatch 2 differs from its predecessor by being free-to-play, which means it will be more vulnerable to players who are up to no good. Blizzard today outlined how they intend to prevent “disruptive behaviour” from players, including the use of SMS verification and machine learning. More awkwardly, game modes will be locked for first-time players, and Overwatch 1’s original heroes will only be unlocked “over the course of approximately 100 matches.”
