Good Apps Factory is looking to combat those nasty everyday germs in their new game Pathogen Defense which is available now on iOS! Pathogen Defense is a mix between classic tower defense games such as The Creeps!, Sentinel, or Jelly Defense and action-strategy games such as Angry Birds and Siegrecraft. In Pathogen Defense your goal is to stop germs from getting past your post. In your artillery you have missiles and power-ups. With each monster you kill, the more experience you gain. This experience can be used to build up your structure in preperation for the next wave of germs.
