Overwatch features characters.
Overwatch (video game) . Overwatch assigns players into two teams of six , with each player selecting one of 24 pre-defined characters , called heroes , each with unique movement , attributes , and abilities , whose roles are divided into four categories : Offense , Defense , Tank , and Support . Additionally , Blizzard has developed and added new characters , maps , and game modes post-release , while stating that all Overwatch updates will remain free , with the only additional cost to players being microtransactions to earn additional cosmetic rewards . Significant time was spent adjusting the balance of the characters , making sure that new players would still be able to have fun while skilled players would present each other with a challenge . The release of the game was promoted with short animated videos to introduce the game 's narrative and each of the characters . Upon official release , Overwatch received universal acclaim from critics , who praised the game for its accessibility , diverse appeal of its hero characters , bright cartoonish art style , and enjoyable gameplay .
