An army of midgets as surprised your forces and taken over each and every one of your base in a single fell swoop. Luckily there was one hidden base left unscathed. But now the midgets have been made aware and are now converging upon it to wipe it off the face of the earth like the others. You must now defend against the base against said midgets. Use your mouse to aim and fire the gun to defeat the oncoming enemies and protect the last base. As you defeat the wave you can level up your gun to better fend off and survive.
