Happy Z-Day

Happy Z-Day is a top-down shooter with tower-defense-like gameplay. Almost everyone in town has turned into a monster, and you must protect your daughter and her birthday party by surviving a set number of nights.

Defend the party

Use resources wisely to construct buildings, upgrade equipment and resupply ammunition, then defend against incoming waves of zombies. The infected enemies have different behaviors, and some types become enraged at night.

Changing locations

Levels take place in locations such as a house, a farm with a barn or a rooftop. You lose if you die or if your daughter's birthday party is destroyed; survive the required number of nights so she can celebrate her birthday.
