Aliens invaded our planet and unfortunately there is no longer anyone else except you. It's hard to say, if you should laugh or cry, but to survive for one more minute, you will have to start acting. You have one smaller plane in the warehouse. Perhaps, if you attach some weapons to it, you can at least put some pressure on them. There are so many of them and shields of your aircraft are not made for such situations. Fortunately, there are ways to improve your airplane. Mining of rare minerals will allow you to research new parts and weapons which will make your airplane aerial threat number one. Create the most dangerous airplane which ever took off from the ground and dominate the skies. Have fun.
