  • Always keep moving. Standing still makes you an easy target for both parasites and infected teammates.
  • Use your Credits to unlock weapons with good range and spread to handle crowds.
  • Keep an eye on infected players; this game has friendly fire that can quickly turn deadly.
  • Stick with teammates for better survival chances, especially during evolutions.
