Smash and Grab

This mission is a three way battle against the Zerg and Tal'darim. The Zerg will constantly push back the Tal'darim, making it the main focus of the map. Your two enemies will mostly be fighting amongst themselves, but will send small assault teams to hamper your progress. Set up a bunker and supply depot to block off your base and deal with any zealot or zerglings that come your way. Your main force should consist of marines, medics and marauders.

With a strong control group together, advance east to the Protoss artifact. They have set up turrets to stop you. In most cases, attack the pylons to stop their power, rather than going for the turrets themselves. When moving be sure to use the attack command, which will make your units stop to defend themselves, rather than suicide march.

Remember to assign your barracks to a control group so you can produce more ground forces and rally them to your growing army. Destroy any Tal'darim strongholds as this prevents them from spawning more forces. While you attempt to take the artifact, the three Protoss statues will activate and assault your troops. However, a good army will easily defeat them.
