Solo Tower – 2D Tower Defense Survival Game Template for Unity

Solo Tower is a complete 2D tower defense survival template for Unity, designed to help you build your own defense or upgrade-based games quickly. This kit features a fully working gameplay loop: survive waves of enemies, earn currency, buy upgrades, and face challenging miniboss rounds.

The tower auto-fires bullets at incoming enemies with varied movement styles, including direct, orbit, wobble, and noise patterns. Enemies attack, retreat, and respawn across randomized waves, keeping gameplay dynamic. Every few waves, a miniboss appears with boosted stats and extra rewards. Players can spend money on upgrades such as damage, attack speed, critical chance, critical factor, tower HP, and regeneration. The game ends when the tower’s health is depleted, with a game over panel showing wave reached and best score.

The template includes clean, modular scripts, ready-to-use prefabs, a retro neon-inspired UI, and a simple menu system with persistent best wave saving. Built for Unity 2021 LTS and the Built-in Render Pipeline, it is easy to reskin with your own sprites, sounds, and styles. No third-party dependencies are required.

Whether you’re learning tower defense mechanics, prototyping quickly, or creating a mobile-ready release, Solo Tower provides a solid foundation.
