Chat with Devs: After the Zerg release, I have been asking Dustin what types of changes are being made to the other factions during this process, and one of the most interesting ones that have been added has to do with the Terran Ghost. In order for the Terrans to counter the various new casters that have been introduced to all sides in StarCraft II, the Ghost can now detect units with energy in a 30 yard radius. This passive ability works similarly to the Sensor Tower, revealing their location even within the fog of war. This ability could also no doubt open up some interesting assassination type single player missions as well with the Ghost.
