Defend the Signal Tower is a fast-paced tower defense survival game set in a striking red wasteland. Waves of enemies advance toward your crystal-powered tower, and every minute survived raises the stakes. You control a defender whose stats can be upgraded mid-run, letting you shape your build around raw damage, movement speed, bounce shots, durability, or increased diamond yield for faster scaling. The battlefield pushes constant decisions: spend currency now for safety, or save for a bigger power spike later. As enemy strength ramps up, smart resource management and timely upgrades are the only way to keep the tower standing. Bright visuals, quick runs, and ever-growing pressure make each defense feel intense and rewarding.
How to play
Your objective is to keep the crystal signal tower alive through as many enemy waves as possible. Enemies approach in groups and grow stronger over time, so defeat them before they reach and destroy the tower. As you fight, you earn currency (₮). Spend it between waves or during combat to upgrade key stats: Damage to kill faster, Max Health to survive longer, Speed to reposition, Bounce to hit multiple targets, and Diamond Yield to increase resource gains for quicker scaling. The longer you last, the more upgrades you’ll need, so prioritize based on what’s threatening you most. Balance offense and survivability, keep upgrading, and hold the line as the wasteland turns into a full-scale siege.
