Alien Siege Game

Aliens have their hands on our people and our goal is to retrieve them back to safety. But to do that, you must first eliminate all the aliens seen in every round. You should be careful as well, because you have to preserve your team to survive the alien siege. There will also be missions per round that you must accomplish to get money. You may also take all the gems in each round for extra cash to be used to upgrade your army. Control your army using the arrow keys or the letters A,S,W,D, aim with the mouse and left click to fire at enemies. If using a mech unit, use down arrow or S to attack. Toggle your group using G, and if your troops get stuck at an area, just press T to make it go to the current area. Use + or – to switch between your troops.
