Hi, I think it could be interesting to put military bases with non-infected soldier inside. They would shoot the zombie but also the survivors which -according to them- could be infected. The soldiers could patrol around the bases in Humvees which would profide to the survivors a high-risk way to get good equipment. That would also strengthen the ambiance of fatality for the survivors which would be killed by the governmental force instead of being safed by them as expected. Thank you for reading, Falanaka
