Can you provide a terran build order for a game of starcraft 2? I'd like to perform a 2 base push with hellion harass in the early game, but I don't know the exact timing of the buildings and when to stop building workers and start attacking
Sure! This Terran two-base push strategy starts with the construction of a Command Center and an Engineering Bay. The first wave of units should be sent towards your opponent's natural base while simultaneously sending Hellions over to their mineral only expansion. You should also begin researching upgrades as soon as possible: Barracks at 11; Refinery at 16; Tech Lab at 21; Armory at 26; and Starport at 32. By this time your economy will likely be strong enough to afford some Marine production, so send those out too. Once all these upgrades are complete, you're ready to attack!

The key to this aggressive build is the use of Hellions and Ultralisks. With a fast-moving force of Hellion/Ultralisk attacks and a few Marines on ground, your Protoss opponents won't stand a chance against you. Your goal here is to take control of their expansions and deny them any resources or reinforcements by destroying any probes that try to run away.
