Blizzard announced a ton of new content for Heroes of the Storm today. Cho'gall, one of the three new heroes coming to the game, is by far the most surprising announcement.
Cho'gall is a two-headed ogre mage who played a prominent role in World of Warcraft. His two heads have their own personalities and voices. Blizzard has decided that the best way to translate this aspect of Cho'gall into gameplay is by allowing two players to control him. Each will have access to a different set of abilities. One player will control movement so you're not just pacing back and forth like a Twitch Plays character.
Everyone attending BlizzCon 2015 in person or via Virtual Ticket will unlock Cho'gall for free. There's an interesting way for everyone else to receive the character. From November 17th to December 1st, you can party up with a friend who owns Cho'gall and permanently unlock the character for yourself by winning two games together. During this period, Blizzard is also giving 2,200 Gold to Cho'gall owners who plays four matches with non-owners.
The other new champion announced today is Genn Greymane. He looks like a normal warrior at first, heading into battle with a sword in one hand and a pistol in the other. However, there's a twist to this character: he can transform into a worgen (basically a werewolf) to access other abilities.
Lunara, meanwhile, is a dryad assassin. She can toss spears at foes and sap their strength with poisons. The trailer from BlizzCon also shows her hurdling an enemy. That ability's going to come in handy on offense and defense.
Blizzard also revealed a new map called Towers of Doom. This battleground varies from others in Heroes of Storm in that you won't directly attack the enemy team's Core to win. Instead, you have to activate Altars throughout the map to capture Bell Towers that will then fire on the enemy team's Core. Your opponents can also destroy these Towers to take them over. It sounds a bit similar to League of Legends' Dominion mode, in that it's challenging players to hold multiple points on the map rather than push lanes.
The last big Heroes of the Storm announcement today was an Arena mode. At the start of the arena, each player chose between three random Heroes. You can coordinate with your team during this selection period and also have more than one of the same Hero on your team.
Players are then dropped into a small map designed around a single objective. Blizzard estimates these fights will only take a few minutes. Once one team destroys the other's Core, a new round will start. The first team to win two rounds will win the match. The layout and objectives of the map will change randomly each round.
