Just as the name implies, Hero-Shooters are games where players can choose from a wide range of heroes, operators, or champions before entering the battlefield, all of whom will suit specific roles and possess unique abilities. While hero shooters have been around for many years, it was really Valve's immensely popular Team Fortress 2 that ushered the sub-genre into the mainstream. Nowadays, the market is flooded with these kinds of titles, all of which range significantly in their quality, gunplay, and most importantly for this list, the number of heroes they offer.
