Add a Wave-Based Zombie Defense Mode
Add a cooperative defense mode in which six to eight players are trapped inside a location such as a house, subway station, shopping centre, warehouse, or restaurant. The team must defend the area against eight to ten increasingly difficult waves of zombies. Key mechanics could include: -Barricades that zombies can damage and break through -Wooden planks and other materials that players must find to repair defenses -Limited supply drops containing weapons, ammunition, medical supplies, and equipment -Strategic resource management between waves -Power outages that force players to rely on flashlights -Environmental details such as emergency television or radio broadcasts After surviving the final wave, players would receive an extraction message and need to leave the defended location to reach a rescue helicopter or vehicle. This final escape would create a tense conclusion instead of ending the match immediately after the last zombie is eliminated.
