A virus killed every man on Earth overnight, and a single bite turns the surviving women into zombies. You're the last man alive: a factory engineer who fortified a rooftop and kept fixing things while the world ended. The survivors who find you become your tower operators, your family, and more. The Last Tower Standing is a real tower defense game with real mechanics, built in Unity with actual 3D combat, not a VN with a minigame bolted on. Every romanceable girl IS a tower: her weapon, targeting behavior, and active ability match her personality.

Intimacy is earned through battles survived together, never bought with currency.
