After exchanging friendly barbs, Findlay offered to act as a middle man between the Raiders and the Möebius Foundation who were buying alien artifacts. The ex-convict revealed Dominion activity on Mar Sara was driven by a dig for such an artifact and it was almost ready to be shipped out. Raynor agreed to raid the dig site and steal it.
The Raiders established a base near the objective. Mar Saran rebels had established another base independent of the Raiders, but were engaged by the Dominion. Raynor wanted to help the rebels while Findlay was content to let the rebels draw away enemy attention.
The Dominion outpost was destroyed and the dig site secured. The Raiders' adjutant gained control of the dig site's crane and brought the artifact to the surface.
The Raiders took the artifact back to Backwater Station for transport off world. Most civilian casualties during the raid were apparently caused by overzealous Dominion troops. Emperor Arcturus Mengsk held a press conference where he justified the policy against the trade in alien artifacts on public safety grounds.
This is the first mission with a controllable base.
Use the starting marines to scout the surrounding. To the north are resource pallets, with enough resources to build a second barrackss; on Hard difficulty and above the pallets are guarded by marines and a War Pig.
Built a tech lab to unlock medics, and train more infantry, and attack toward the besieged rebel base in the south-west corner. The rebels may be overwhelmed by the Dominion without help. Reaching the rebels provides controllable reinforcements in the form of surviving rebel units and buildings, including a barracks.
The enemy base in the north-west corner. Approaching it triggers an attack by defending hellions. In Hard difficulty, there is a Devil Dog in the base. On Brutal, there is a siege tank in siege mode in the base.
Collecting all 9 resource pallets unlocks the level's second achievement in Normal mode.
