Gamertell has posted its hands-on impressions of Take-Two's Bioshock 2 that was demonstrated at CES 2010.
"Players will be able to equip two weapons and two plasmid powers such as Telekinesis or Incinerate. The super powers can be used to activate vicious combos causing ridiculous amounts of damage. For example, combining water and electricity does large damage. The plasmid power Incinerate has a dramatic effect on a map with oil slicks on it."
