You should choose this upgrade if you are not confident in your macro. It will mostly remove some macro difficulty and save some attention span, but not actually bring much in-game benefit. Orbital Depots is mostly an upgrade of convenience. Refineries and Automated Refineries produce vespene gas 25% faster.

It's also important to note that this upgrade will apply to all units, not just those that can attack. Since turtling is more reliable in the single player campaign, it could be more important to make sure your army survives than to kill the enemy faster. The Terran's ability to repair & heal units means that this upgrade is worth more than just 5% life units that survive a battle because of this upgrade can be fully repaired, providing more cost-efficiency. Sometimes it also simplifies microing: for example when fighting a Drone or Zergling, a Reaper can stay put and fire another shot instead of stutter-stepping away.Ĭhoosing Vanadium Plating will greatly increase the resilience of your units. This upgrade becomes more valuable if you build Bunkers, because it applies to the units loaded inside. Indeed, if you make heavy use of stutter-step, this upgrade will be of little use, as your units will fire at the rate you -order them to, which is always slightly lower than their max rate. This upgrade will be most useful when you are not micro-ing your units. However, it should be taken into account that it increases the rate of fire, not the damage per shot. Armor upgrades in the Armory and Engineering Bay increase life by 5% in addition to increasing armor.Ĭhoosing Ultra-Capacitors will increase the damage output of your units, which is very good.
