At BlizzCon 2015 it was unveiled that more Heroes including - Lunara Bluetear, Genn Greymane and Cho'gall will join the game. Plus Towers of Doom a brand new battleground will be added. The game will also feature a new mode called Arena that pits two teams of five against each other in best-of-three competition.
When you enter the Arenas, you must select one of three random heroes before each match starts. Players can see all the choices available to their team mates and coordinate the picks.
Once you enter the Arena and choose your Heroic Abilities you must ride directly into battle to capture temples or topple Garden Terrors on their quest to destroy the opposing Core.
Once a Core has been obliterated to end the round - and each round lasting only a few minutes - all Heroes will be transported to a new Arena, and the next battle will begin. The first team to raze two Cores will achieve victory, earning the adoration of the Nexus denizens watching from the stands.
