In earlier builds, Anti-Gravity could affect destructible doodads, but this was a bug. Sentries dealt bonus damage against biological units. Earlier builds featured an ability called Null Void. * Null Void * Ability Cost: 50 Image:Energy Terran SC1.png * Prevents any unit caught in the target area from using abilities that cost energy. It does not affect abilities such as a stalker's Blink, a carrier's Build Interceptor, a Phoenix's Overload or an SCV's Repair. Immediately upon exiting a field a unit can use its powers like normal. * Nullify acts as a detector, decloaking units such as ghosts and dark templar and revealing burrowed units. The ability to detect cloaked and burrowed units was being subjected to balance testing. * The effect lasts 15 seconds.
