Co-op Commander Preview: Zeratul

Co-op Commander Preview: Zeratul


Zeratul’s gameplay will revolve heavily around the Prophetic Vision ability, which allows the player to discover three Xel’Naga Artifact Fragments on the map. Players are encouraged to seek out these Artifact Fragments as they will improve Zeratul in a variety of ways:

  • Zeratul, his units, calldowns, defensive structures, and even Probes will gain weapon, armor, and shield upgrades with each Artifact Fragment.
  • Zeratul has no traditional researchable abilities. Instead, Artifact Fragments he finds will grant his units Artifact Enhancements, which are either new abilities or improvements to existing abilities.
  • Zeratul has a potential of four top-bar abilities, but only one is unlocked at the start of the game. Players unlock new top-bar abilities with each Artifact Fragment they find.
  • The Legendary Legion calldowns improve with each Artifact Fragment found.
  • Zeratul himself gains bonuses.

In addition, uniquely among Commanders, Zeratul’s top-bar will be fully customizable. Both at the start of the game and with each Artifact Fragment recovered, you’ll be able to choose one additional top-bar ability from a selection of two or three. Players should select these abilities carefully based on both their individual playstyles and the needs of the mission.

Design Philosophy

We’ve always been huge fans of Zeratul as a character in the StarCraft universe, so we knew we wanted to bring him to Co-op. However, we already had a “Dark Templar” Commander in Vorazun, so we had to take special care to make Zeratul feel different enough from his Nerazim counterpart.

Right off the bat, we knew we wanted to have Zeratul as a controllable hero on the battlefield. And we wanted him to have a small elite fighting force, as he was most often featured in insurgent-style missions in the StarCraft II campaign. But we also knew this wouldn’t be enough, so we played the campaign to really dig into Zeratul’s identity beyond the fact that he’s a Dark Templar.

Throughout the campaign, Zeratul looked to the wisdom of the Xel’Naga for guidance, obsessed with finding their prophecies. We experimented with how we could incorporate this into his Commander design and eventually came up with the Prophetic Vision ability, which allows players to pierce the void to find the locations of procedurally-placed Xel’Naga Artifact Fragments hidden on each map.

In addition, we were committed to creating a Commander that felt and played differently from his Protoss brethren. To that end, Zeratul’s army will receive unique Xel’Naga enhancements, which should hopefully allow players to see traditional Protoss units in a completely new light. Our intention is to make Zeratul feel like a Xel’Naga Commander as much as he does a Protoss Commander.

Finally, during our playthrough of the campaign, we found that Zeratul had a curious habit of finding allies who were more than willing to sacrifice themselves for his sake. Inspired by this, we created the Legendary Legion calldowns, which allow players to call in reinforcements from other Protoss factions (often to send them to their deaths).

Top Bar Abilities

A level 15 Zeratul will have 3 choices for each of his top bar abilities. Adapt to the enemy and your mission objections and select your powers accordingly.
