Gameplay
The Protoss campaign will be based on diplomacy as the Protoss factions splinter. The player will work with different Protoss tribes which will help them gain allies and advance the plot, but at the same time making them enemies with other tribes. The ultimate goal of the campaign is to unite the various tribes into a viable, unified force that can ensure the Protoss' survival.
Chris Sigaty has expressed doubt that new units will be added to the game, as was done in Heart of the Swarm.
