The "Misconception" Achievement requires you to
destroy 25 infected water towers before they hatch. Do
this after you get your powers back -- when Ragland helps
you -- as there seem to be more of them in abundance.
Lock on to one and run up the corresponding building,
jump to the roof and use the flying kick attack, causing
more than half of the life bar to be depleted. Upon
landing, follow up quickly with a combo. To make it a
little faster, use the "claws" powers.

Later in the game this becomes even easier. Just
hijack a helicopter, fly over infected areas and keep
tapping the target button until you target a water tower (or helicopter or Hive)
and fire away.

The "Friendly Fire" and "Projectiles" Kill Events as both have helicopters sitting next to the Event markers, so grab those and exit the event for a free 'copter.
