Something gone very wrong, your friendly outpost just attacked your convoy and most of your pilots died instantly. You crashed on the planed and your aim is to move around, kill dangerous aliens , grab various items and solve missions. Use "W", "A", "S", "D" KEYS to move, and press SPACEBAR to change your weapon. Use YOUR MOUSE to aim and click LEFT MOUSE BUTTON to shoot. There is lighter area at the end of the screen which shows you can go to the next screen. Use inventory at the bottom bar to see mission briefing or see access code in deck 1 tower. Be careful, machine gun ammo is very limited. Good luck!
