Next we have the Zergling, the Zerg's most-produced unit by far.
Researching Charge lets them enter the battle much more quickly While not the unkillable, godlike creatures they were in Brood War, Starcraft 2 Zealots offer great health per resource, and like the other basic units, their research upgrade (Charge) gives them new life in the midgame. All three units are foundational to their race's identity in the Zealot's case, its high health but relative slowness represent Protoss's strong, immobile style. We'll start with each race's basic unit - the first combat unit you can make, costing only minerals. Today, I want to take you through these units, what makes them so unique, and how they come together to give Starcraft 2 its endless depth and longevity. Starcraft sets itself apart from other RTS games in its unit design - where other games have a simple rock-paper-scissors strategy, Starcraft and Starcraft 2 both feature a cast of unique units, with their own special attributes and abilities.
