Neighborhood Defense
Neighborhood Defense
Neighborhood Defense is a dynamic tower defense strategy game where your mission is to protect your neighborhood from waves of zombies. Diverse maps with multiple exits, different types of enemies, and limited tower spots make each match unique. Upgrade your towers, combine their abilities, and plan your tactics carefully to stop the horde and prevent them from breaking through.
Instructions:
At the start of each level, choose free spots to place towers: archers, bombers, snipers, or electric turrets. Each tower has three upgrade levels that increase damage and attack range. Watch out for zombie waves — warnings will show where they appear. Focus on blocking key paths and managing your resources wisely to hold back stronger enemies. If too many zombies break through the exit, the game is over.
