after destroying the prison, well at least thats what you thought you did. you didnt and the gas leaked out and attacked the city. you need to find all supplies you can get from the city (remember blockages have been put out by police in their attempt to stop the infested) you need to get to the gun shop, hospital and you need to find the biulding where the blue key is to get to the military base. before you get to and inside the military base the infested grow stronger and become different in other ways. once inside find the plane to get you out of here and have a look around you may find some wepons. there maybe some survivours out there FIND THEM!
