Although it’s been focused on its smash hit multiplayer shooter Overwatch lately, Blizzard Entertainment has managed to keep its blockbuster real-time strategy game Warcraft III up-to-date since 2002 with annual patches. Now, it’s set to make waves again with a tournament. The first-ever ‘Warcraft III Invitational’ will see well-known players from around the world go up against each other at Blizzard’s headquarters this weekend.
