The re-emergence of Raynor's Raiders, another anti-Dominion group, provided Tosh with another opportunity. The spectre hired the Raiders to go and mine Redstone's minerals as well. Tosh sold the operation as a way for the rebels to make badly needed money, and did not reveal his ulterior motive. The planet's frequent lava surges and zerg presence made this an unconventional mining operation.
Tosh provided assistance remotely. He reinforced the Raiders with reapers; additional units were operating in the vicinity and waiting top link up as well. The spectre provided directions to the last known location of the contracted miners and additional mineral fields. Even with these additional resources, Matt Horner reminded Raynor to carefully manage expenditures to avoid drawing too deeply from minerals being amassed. The rebels promptly departed once their quota was reached.
The low ground, where the minerals are, is regularly flooded by lava surges. On all difficulties, except brutal, a timer displays the time to the next lava surge. Even without the timer, the lava will glow brightly and warning sirens will sound to warn of an imminent surge. Units and structures caught in lava are destroyed. Use lift off to protect mining bases on the low ground.
Reapers are adequate for most opposition. Destroying zerg bases is optional, but destroying hatcheries yields resource caches. The zerg do not attack in great strength. Attacks and base defenses may include mutalisks; train marines to support the reapers. On brutal, the zerg base in the map's north-east corner contains infestors and a brood lord. Defend mining expansions accordingly.
Four reapers are received as reinforcements, and the ability to train more, early in the mission. More reapers, and resource caches, are scattered around the map as rescuable units. The reapers' speed and ability to jump up and down cliffs makes them ideal for the map's multi-level terrain. Use the first reapers to move to the north and find a rescuable command center and five SCVs; the command center may be loaded with the SCVs to form a mobile mining base on the lower ground. A group of reapers may be found further to the north-east.
The brutalisk in the map's south-west corner guards resource caches. Killing it yields research points, and an achievement if killed by the lava. Marines, marauders and medics can easily kill it. To kill if with the lava, attack and withdraw to lure it into the low ground. Pause regularly during the withdrawal to allow the brutalisk to catch up and entice it to keep pursuing; moving too fast will cause the brutalisk to return to its lair. The brutalisk has to arrive on the low ground shortly before a surge.
Another way to kill the brutalisk requires shrike turrets on bunkers. Building one of those, along with various structures such as missile turrets or supply depots, will keep the brutalisk attacking until all structures have been destroyed. Thus, it will stay, even when the lava starts rising.
Use lava to finish Brutalisk on Normal difficulty.
Send reapers to the brutalisk with less than 30 seconds before a lava surge. Head to the right ramp and attack from a distance as necessary to keep the brutalisk's attention, once down to 5-10 seconds jump the ridge to the right where the zerg base is.
Diablo, from Blizzard's Diablo series, is on an island at the south-east corner of the map. It is unselectable and can be seen only by moving a flying structure, air unit, placing a scanner sweep or placing a unit at the right point on the cliff border.
