If the game freezes, just click inside it (games can get unresponsive if you click elsewhere on the page).
Use your armory of weapons to defeat a well-defended army of mechanized drones capable of attacking from the ground and air. Keep the gold mine operating and you'll be able to upgrade to better weapons. Receive medals for destroying the bots, advance deeper into the mine and defeat your enemy in a final climactic battle.
