Let's address the elephant in the room. As of 2024/2025, Blizzard (now under Microsoft) has not made the StarCraft II trilogy free-to-play. The first campaign (Wings of Liberty) is free, but Heart of the Swarm and Legacy of the Void are paid expansions.

The StarCraft 2 series is set in a distant future where three species, the Terrans, Zerg, and Protoss, are fighting for dominance in the galaxy. The games follow the story of Jim Raynor, a Terran rebel leader, and his battles against the oppressive Terran Dominion, as well as the Zerg and Protoss threats.

The final chapter focuses on Hierarch Artanis and the Golden Armada. This campaign introduces the "Spear of Adun" – a top-down tactical ability system that lets you call in orbital strikes or warp in elite units. It also includes the Epilogue missions ("Into the Void"), which conclude the 20-year storyline.
