Liberation Day

You'll start on a dusty road along Mar Sara's wasteland. Your small squad will consist of five basic marines and Jim Raynor. Raynor is a hero unit, giving him special stats to be more powerful in battle. For this mission he must survive until the end.

Select all of your troops and march down the road. Along the way you'll encounter Dominion marines, so stop your advance and defeat them. You'll soon arrive at a town center that is heavily guarded by enemy forces. Thankfully, a squad of allied reinforcements will land and distract the enemy. Use this chance to kill off the remaining Dominion and add the new marines to your controlled squad.

There is a secondary objective to this mission. Stop and search for Dominion billboards and projections that spout audible propaganda. There are five scattered around the area and will unlock bonuses for destroying them. When ready, continue along the road.

You'll come to a transport that is shipping off innocent colonists. Kill the marines and then takeout the transport vehicle itself as it has a mounted turret. The colonists will now support you for the remainder of the mission. With your increased numbers, march towards the enemy stronghold and destroy everything along your path. When the base is taken, the mission will end in victory.
