Brothers in Arms

Brothers in Arms is a mission in the campaign of Legacy of the Void, and the second mission in the Korhal storyline.

Background
While Hierarch Artanis and Commander Raynor were occupied stabilizing Sky Shield, Moebius Corps raided Korhal Palace and stole the Keystone. They retreated to an entrenched position at Bennet Port, where they were preparing to take the artifact off world.Valerian Mengsk, Jim Raynor and Artanis sent forces to intercept them.

Mission
Raynor and Artanis arrived and set up their bases, with Valerian's forces getting delayed. Several hybrid dominators began channeling void energy into the keystone, stunning all terran forces on the field but leaving the protoss and the hybrid unaffected. In order to combat the hybrid Artanis deployed immortals to provide heavy assault support. Valerian noted that there were research stations with personnel that were unable to evacuate. If Artanis helped them, Valerian would return any protoss technology within, including some solarite.

The combined Daelaam/Dominion force broke through the Moebius Corps and hybrid position, destroying the containment unit housing the Keystone. Artanis warped the artifact aboard the Spear of Adun.

Aftermath
""Damn, look at this place. Even the zerg didn't tear into the city like this."

- Jim Raynor on the ruins of Bennet Port

Moebius Corps and the hybrid were driven off of the planet, but at great cost to the Dominion. Augustgrad was in ruins, with countless terrans dead. Valerian and Matt Horner surveyed the dead and aided wounded. Artanis and Raynor looked upon the destruction, and Raynor said that if Zeratul believed he could make a difference, then the fight had just begun. Raynor and Artanis shook hands, and Artanis was warped aboard the Spear of Adun.

Walkthrough
The player spawns in the southwest corner of the map, with Raynor and Valerian's bases to the north and east respectively. The player must push with the allied Dominion forces to the artifact in the far east. At certain intervals the Keystone will stun all terrans on the map and a wave of hybrids will push. This opportunity can be used either to defend the terran bases or to push into the Moebius bases and destroy their structures. Rescuing the research teams will both provide solarite and spawn support units for the allied terrans. As the Moebius bases are destroyed, allied Dominion forces will set up outposts, letting them push in further.

A force of immortals and stalkers can break through the Moebius lines, as they excel at destroying the heavily armored hybrid and take down buildings fast. As the allied terrans will usually be outgunned, it is recommended that the terrans be defended from the hybrid wave during the global stun, and whatever time is left can be used to destroy the Moebius bases.
