1. I believe that the zombie that acts like a 'shield' or becomes immune for a short period of time basically already is an armored zombie. One thing I would like to see, however, is this zombie still being able to attack after its ability is activated and it not being able to be frozen when it is immune.
2. Considering that some parts of the gameplay are already unbalanced, I believe that incorporating force field grenades would be a terrible idea. You could easily avoid zombie confrontation and, especially higher level players, would have way easier opportunity to avoid getting killed.
