Real-Time Tower Defense

Base-building tower defense

Real-Time Tower Defense is a PC game that combines tower defense with real-time strategy. You build a base on a grid to supply an army that fights automatically: factories produce units, which march toward the enemy without direct control. Up to 10,000 units can fight on the battlefield at once.

Mines extract three types of ore and transport it to your buildings. Towers need ore to keep firing, while factories spend it to produce units. Gold flows into your main building for upgrades. Each piece of ore can only be spent once, so expanding your defenses, producing an army and upgrading your base all compete for the same resources.
