Lock & Load

Lock & Load is an Co-op Missions scenario in Legacy of the Void, added in Patch 3.1. The map is taken from the Legacy of the Void campaign mission Temple of Unification, but the missions objectives are different.

Background
When the Daelaam, Zerg Swarm, and Terran Dominion returned to Ulnar to enter the Void and face Amon, Amon's forces attempted to destabilize the planet's celestial locks to overload the planet's energies and destroy it, which would prevent their entry. Rohana led the defense of the locks.

Gameplay
This mission has players spawn on the southwestern corner of the map. Over time Amon's forces will move out to claim a celestial lock, beginning to overload the planet, represented by a bar in the upper-right corner of the screen. The more celestial locks Amon's forces control, the faster the bar fills. If the bar fills, the mission is lost. The players must clear the celestial locks of Amon's forces to claim them, which requires at least one unit of both forces to be present. Even if a locked is claimed by the players, Amon will send forces to retake them. The mission is won when all five locks are claimed by the players.

During the mission a xel'naga construct spawns in the northeastern end of the map. It can be destroyed to earn bonus exp.
