Get to Know About Underground Invasion
Underground Invasion plucks you below ground to face wave after wave of attackers in narrow tunnels. You set up turrets. You weld new parts from gathered ore to boost their firepower. Enemy groups advance from all sides and pressure grows with each wave. You scout choke points and reinforce walls to hold the line.
You upgrade towers with earned resources and unlock new skills with each win. Some foes take heavy hits. They fall only after sustained damage. Other attackers break apart under repeated strikes. Tunnels bend and curve to force new layouts. This underground setting keeps each battle from feeling familiar.
You can play on Silvergames or Kongregate. Each skirmish demands quick thinking and careful planning. Tower defense fans and strategy seekers will enjoy a steady challenge from the first fight to the final stand.
