On October 29, 2019, Blizzard announced the open beta for Warcraft 3: Reforged, a recreation of Warcraft 3: Reign of Chaos and it's expansion, The Frozen Throne.
Warcraft 3 is the RTS game Blizzard made after Starcraft that spawned the MOBA genre with it's custom game mode, Defense of the Ancients.
Players who want to experience the nostalgia now can pre-order the Spoils of War edition to unlock a Meat Wagon Mount, a Hearthstone card back, several skins and characters for Starcraft and Heroes of the Storm, a pet Mal'Ganis for Diablo 3, and some icons and animated sprays for Overwatch.
Players who pre-order the game will also be guaranteed a spot in the beta. Invitations will go out to additional players after those are sent out. You can check the announcement here, and preorder the game at the link below.
