The MULE is still in the prototype stage and has a limited battery life. The Dominion Fleet deploys these machines via drop pod. Once deployed, a MULE will collect resources three times faster than an SCV—a fact that some SCV pilots don't take kindly to hearing. When MULEs ran out of power, SCVs could provide more to them to get them started once again. To many SCV pilots, the MULEs were frustrating to work with, for they required a lot of correction in guiding their powerhouse excavators to drill correctly.
MULEs are summoned by the orbital command's Calldown: MULE ability. Each drop pod contains one MULE. A MULE takes about three times longer to finish mining a load than an SCV, but retrieves 25 minerals per load, meaning that it collects minerals approximately twice as quickly as an SCV (SCVs retrieve 5 minerals per load). A MULE and an SCV may mine from the same mineral patch simultaneously. MULEs last 64 seconds before shutting down, and can be called down anywhere on the map with player vision. As it takes slightly under 64 seconds for orbital commands to recharge 50 energy, one orbital command can call down a new MULE as the previous one expires.
MULEs mine the same amount from high yield mineral patches.
A MULE summoned directly onto a mineral patch will harvest 270 minerals before running out of energy.
In addition to mining resources, MULEs can also be used to repair units. While this is an inefficient way to use them in comparison to using them to mine, they can be used in emergencies to keep mechanical units alive during battles. Another use of MULEs is to drop them near enemy units that inflict friendly splash damage, such as siege tanks, causing disruption and friendly fire.
An orbital command summons one MULE via drop pod. If the ability is targeted on a mineral patch the MULE will begin mining automatically, extracting 45 minerals per trip. The ability may be used only on areas uncovered by the fog of war.
Damaged mechanical units recover hit points when out of combat, at a rate of 0.6015 each second.
Our ship and vehicle hulls are now made from a material called Regenerative Bio-Steel. This material uses internal nanobots to slowly repair any damage the hull sustains. While this regeneration process is much slower than conventional SCV repairs, it can be the difference between life and death if no SCVs are available.
Armor upgrades increase health of affected units by 5% per level.
We have created a new lightweight alloy called vanadium. Vanadium diffuses weapon impacts much more efficiently than traditional armor plating, and it better preserves the life of our units. Now each of the armor upgrades in the armory and engineering bay increases unit life by 5% in addition to increasing armor.
MULEs harvested 42 minerals per trip from rich mineral patches prior to patch 1.4.3.
MULEs were temporarily removed from Legacy of the Void in patch 2.5.5. They were returned in the subsequent update patch, albeit with the calldown now set to autocast. They were returned to how they functioned in Heart of the Swarm in a subsequent update.
In a Legacy of the Void design update, MULEs were planned to be able to mine vespene gas, but would have lose efficiency if more than one MULE was assigned to a refinery. They would have harvested 10 gas per trip. To offset this, their ability to harvest minerals was to be reduced to 20 per trip. This change was reverted before it could be implemented in-game.
Call down 30 MULEs in a single Unranked or Ranked game.
↑ 11.011.1True, as long as you have line of sight on the spot, you can drop MULE. On the enemy's Siege Tanks, on a ramp, etc. However MULE can't attack or repair. Cydra. 2009-04-23. Blues -- can the OC call down mules anywhere?Battle.net StarCraft II General Discussion Forum. Accessed 2009-04-24.
