Alpha testers will begin with a short player tutorial on the basic functions of the game, such as character movement and a slight intro to tactics. A list of both obtained and daily quests can be found in the quest log, which grant experience points that advance your level and power. Some quests can even unlock special features and modes. Following the format established by games such as League of Legends, HoTS will have players purchasing heroes with either in-game gold or real world currency. Players can however, elect to try out each hero in a solo practice match before making a purchase, during which they have complete control over such things as ability cooldowns and enemy spawns.
Players will begin battle in Practice Mode, which pits them with 4 AI teammates against a full team of AI enemies. This provides the an initial opportunity to get used to the games mechanics without the pressure of competing live although it may annoy some of the more veteran MOBA players. Ranked play was mentioned, however it will not be available during the tech alpha.
A talents tab was briefly mentioned, and seems to allude to players being able to change what traits their hero gains at each level, however like much of Heroes of the Storm, this is expected to change quite a bit through development.
