Alien invasion has begun! You control the last platoon of soldiers that have survived the onslaught! Protect your bases! Once all the bases are destroyed the aliens will control everything! 5 stages, 10 waves each stage, and a big bad alien boss at the end of each stage!

Last Platoon is controlled by mouse. Click on one of the game icons at the bottom of the screen to pickup that item (if you have enough gold to buy it). To purchase that item click once again on the game background to place that item on the ground on the left side. If you change your mind and do not want to purchase the item you have picked up you can click the game icons at the bottom again to let go of that item.
