Adding weather to the game would be a great implement, would make the game more realistic. Rain and thunder would make the roads slippery and we would have to be more careful when driving. There could be a small percentage of temporary power outages during thunderstorms and that percentage would increase according to the difficulty of the game but the idea is to be rare in standard mode. Snow would make the zombies slower and the players too, but there could be boots to equip the player so that he would not be affected by the snow and in extreme situations the zombies could freeze. Fog made it difficult to see, but it would only appear in the morning and during cold seasons. Now the sunny days became as the game is now or even brighter and the player would have a good view of their surroundings. It would be cool to end infestations or an attack on the base and in the background hear thunder and lightning.
