Aliens invade...

again!? It's time to teach them a lesson they'll never forget.

Your task is to make them remember it for good using a small squad of troops. You can command the entire squad or control each soldier separately.

Order them to guard an area and go scout the surroundings by yourself, then strike the aliens with all the firepower you have.

Blast them with grenades, run them over with cars. Your troops get promoted and their skills improve with each completed mission.

Turn the trembly and gawky novices into hardened killing machines.

And don't let the aliens do anything nasty to the innocent sheep caught in the middle.
