2 Factory Vulture

A mech-oriented TvZ build that opens with a fast expansion into two factories, each with a machine shop. The core idea is to use vultures for aggressive map control — planting spider mines at expansion paths and harassing drone lines. Research spider mines first, then ion thrusters for vulture speed.

Key timing: your first four vultures should be on the map by the 7-minute mark, mining key chokepoints. Use vultures to scout and deny Zerg's third base. Transition into siege tanks once you have map control, building toward a standard mech composition.

This build excels on large maps like Fighting Spirit where vulture speed and mine coverage matter most. It struggles against fast lurker timings if your mine placement is poor, and against early mutalisk switches that catch your turrets incomplete.
