What is Invasion of ancient monsters

A prehistoric apocalypse is unfolding, and only you stand between the ancient monsters and total destruction. Gear up, aim true, and survive as long as you can.

How to Play

Tips for Playing

  • Learn each monster's attack pattern to dodge more effectively.
  • Don't hoard currency; buy upgrades early to boost your firepower and survivability.
  • Use the environment to your advantage, funneling monsters into narrow paths.
