Go to one of the planets to extract important resources with the help of battle towers. They not only can take resources from the depths of the planet, but also protect themselves from the invasion of monsters. Enemies are very fond of iron, so your towers will be to their liking. To start the prey, install the first tower that can shoot with a laser. As soon as the enemy approaches her, he will immediately be destroyed. With the destroyed monsters, ingots are falling, which are necessary for the construction of new structures. You can not only install new towers, but also improve existing ones. With each wave of enemies will be more, so consider a defense strategy in the game Surge.
