Happy Z-Day — another strategy with elements of horror, where the player will tell the story of the main character, the father of the girl whose birthday is today. Something happened in this city. Almost everyone turned into a monster. You need to protect your daughter and her birthday. Happy Z-Day is a game defense, similar to Tower Defense, in the style of shooting from top to bottom. The game takes place at home or on a farm with a barn or even on the roof.
