SCVs can patrol, a very useful ability considering they can auto-cast repair. While multiple SCVs are able to simultaneously repair a unit/structure, only one SCV can construct a structure at a time due to reasons of balance. SCVs may repair any allied unit that is considered mechanical regardless if it is terran or protoss, but they can only repair terran structures. It is the only terran multiplayer unit without a ranged attack.
Applies your currently selected spray or decal to the terrain at the target location. Creates one charge every 14 seconds for a maximum of three charges. Each player may have only five sprays on the map at a time.
This ability does not have a description in Versus mode.
Multiple SCVs can build a structure. Each additional SCV reduces build time. Building cost remains the same.
This revolutionary computer allows multiple SCVs to work on the same structure simultaneously. The onboard assistant is so efficient at coordinating SCV efforts that building costs are unaffected. This upgrade is vital when trying to get a base up and running quickly, or when trying to rebuild a broken defense.
The SCV's ability to get damaged mechanical units back to full life, and even to repair units while they are taking damage, has been a key advantage over the protoss and the zerg. The Dual-Fusion Welder allows SCVs to repair at twice the speed, improving their ability to keep damaged units alive in the heat of battle.
We can now call down supply depots straight from orbit due to our new understanding of protoss architecture. Key point joints have been added to the supply depot's structure, allowing the supply depot to survive the violent turbulence of breaking through an atmosphere. Now an SCV simply has to place a beacon, and the crew on the Hyperion will handle the rest.
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.
