The standard units in StarCraft II are great and all, but sometimes you want to call in a little extra firepower. Enter: the mercenaries. While you’re in the cantina you can head on over to Graven Hill’s table and check out all the latest guns-for-hire. After you pay a modest fee for one of their contracts you’ll be able to call in your newly acquired mercenaries from the Merc Compound, and they’ll be dropped into the battlefield immediately. Like the upgrades they aren’t game breaking, but they are a welcome addition to an army of any size.
