Defend your base from relentless waves of enemies by building a powerful and carefully planned tower defense system. Your main objective is to stop every attacker before they reach the end of the path, using smart placement, timing, and upgrades. Each wave grows stronger and more unpredictable, pushing you to think ahead and adapt your strategy as the battlefield evolves.
A wide selection of towers gives you the freedom to create unique defensive setups. Sentry towers provide steady and dependable fire, making them ideal for early defense. Sniper towers excel at long-range precision, dealing massive damage to high-priority targets. Cannon towers unleash explosive blasts that are perfect for clearing groups, while Freeze towers slow enemies down and create valuable breathing room.
Laser towers deliver constant damage over time, and Mortar towers strike from a distance, punishing large enemy formations before they get too close. Combining these towers effectively is the key to long-term survival. The game features more than 80 challenging waves spread across multiple maps, each with its own layout and tactical demands.
Three difficulty modes allow players to choose between a relaxed strategic experience or a demanding test of skill and planning. As you progress, you can unlock achievements and compete on global leaderboards, adding a rewarding sense of progression and competition. Every decision matters, especially as enemies become faster, tougher, and more resistant.
One of the most intense moments comes with the Enraged Titan boss fight, a true test of your defensive mastery. This massive enemy requires careful preparation, efficient tower placement, and strong synergy between your defenses to defeat. Only well-balanced strategies can withstand its overwhelming power. The controls are designed to be simple and accessible. Use the mouse to place and select towers, open the shop to purchase new defenses, and start each wave when you are ready.
