It’s the perfect time for players new and returning to get into Heroes of the Storm. Announced yesterday in advance of the Heroes 2.0 launch event, Blizzard revealed that they will be giving away ‘mega-bundles’ of 20 heroes for free if players logged in between April 25 and May 22.

Each player will be granted a selection of Mega Bundles of heroes from Assassins, Flex, Support/Specialists, and Tanks/Bruisers.

Here’s a full rundown of heroes included in each set. :

Assassins: Alarak, Chromie, Falstad, Greymane, Gul’dan, Kael’thas, Kerrigan, Li-Ming, Lunara, Nazeebo, Nova, Raynor, Sylvanas, The Butcher, Tracer, Tychus, Valeera, Valla, Zeratul, Zul’jin
Flex: Abathur, Arthus, Azmodan, Brightwing, Diablo, E.T.C., Greymane, Johanna, Kerrigan, Li LI, Li-Ming, Lt. Morales, Nazeebo, Rehgar, Rexxar, Sylvanas, The Lost Vikings, Tychus, Varian, Zul’jin
Support: Abathur, Auriel, Brightwing, Chen, Dehaka, E.T.C., Johanna, Kharazim, Li Li, Lt. Morales, Lucio, Malfurion, MEfivh, Murdadin, Reghar, Stitches, Tassadar, Tyrael, Uther, Zarya

Players will automatically receive 100 gems when they log in to Heroes between April 25 and May 22, letting them purchase the bundle. Once you unlock one bundle, the other three become unavailable.

Note that there is some crossover between sets, so you’ll want to make sure you’re picking up the one that grants you the most heroes if you’re returning after a break. New players should stick to the playstyle that they want to learn.

Heroes of the Storm 2.0 will launch on April 25. Blizzard will be hosting a livestream launch event on the 25th at 11AM PDT on the Blizzheroes Twitch stream.
