You can score a free Mechanospider mount for Heroes of the Storm using a new social application made by Blizzard called Team Builder. The special experience suggests the best characters for a team made up of your Facebook friends and, at the end, offers a unique code that can be redeemed for the epic mount in the game.

Heroes of the Storm saw the release of its final version earlier this week, and alongside the actual game, Blizzard also rolled out plenty of festivities and goodies for old and new players of the online title.
Get a free Mechanospider mount in an easy way

After having brought new rewards for HotS users in other Blizzard titles like Hearthstosne: Heroes of Warcraft or World of Warcraft, Blizzard now shares on its website a special social application designed to offer players a free Mechanospider mount for use in Heroes of the Storm.

The catch is that you must use the Team Builder to create a HotS team with your Facebook friends. After picking a few attributes for you and your buddies, the program then shares what characters best suit your descriptions.

"Form your ultimate quintet and reveal the inner Heroes of you and four of your Facebook friends with the Heroes of the Storm Team Builder! Choose which friends you’d want to accompany you into the Nexus, and then follow the instructions to assign traits that describe your pals—you can be as silly or as serious as you like," the studio explains.

Most importantly, after the process is all done, you get a code that can be redeemed on Battle.net for a free Mechanospider mount that can be employed by all of the characters in Heroes of the Storm. As you can see in the brief video below, the mount comes in three color variations that get unlocked as you level up your heroes.

Don't forget that you must also enable the mount for each hero before jumping into a match.
