Atlantis is a space style shooting game where your job is to kill the enemy before they kill you and they take down your mothership. Use WASD keyboard keys or keyboard ARROW KEYS to move around. Use YOUR MOUSE to aim and click LEFT MOUSE BUTTON to shoot. Use 1-4 NUMBER KEYS to switch weapons an use "Q" and "E" KEYS to select gun modes. When you are out of ammo or your health is low, return to Atlantis to get repaired and reload by standing inside blue light. After reloading (if you have enough energy) you can upgrade your Robot by standing inside yellow light.
