Three new heroes, an Arena mode, and a new Battleground are coming to Heroes of the Storm, Blizzard has announced.

Lunara is a dryad ranged assassin, Grey Mane is a Worgen warrior, and Cho’Gall is a two-headed warrior/assassin ogre. The latter is controlled by two players simultaneously.

Meanwhile, Towers of Doom is the new Battleground, and players will be urged to capture cores by Raven Lord or the Grave Keeper.

Each Core is protected by a barrier that cannot be destroyed by Heroes. Instead, teams must clash to activate the Altars that rise within the town. Once an Altar is claimed, each of the capturing team’s Bell Towers will fire on the opposing Core.

Six Bell Towers in total guard the Battleground – but their allegiance is fickle. Upon destruction, a Bell Tower will turn against its former allies, each adding one more payload to the explosive volley that will fire when an Altar is captured.

Finally, the new Arena mode will pit two teams of five against each other in best-of-three competition. According to Blizzard, these fierce, close-quarters skirmishes will take place on an ever-evolving field of battle.

All who enter the Arenas must select one of three random heroes offered to them before the start of each match. Players will be able to see all the choices available to their teammates and coordinate on these Hero picks.

Once players enter the Arena, they’ll choose their Heroic Abilities and 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. There is no limit to the number of times a Hero can appear on each team’s roster.
