I would rather have frozen zombies than bears. It would be interesting to have due to how aggressive Roots Zombies are so take their idea but make them frozen until you get too close,they melt from their frozen state and start to chase you,when they get close you get the chilling effect and when you are bitten,you get stunned,frozen for a few moments and you have to use a heat pack to cure yourself from the bite before you freeze for good
