Winner of all hearts and the competition orchestrated, the spinoff of the space themed science-fiction action FPS game Invasion developed by CDIS Lab. which takes place at the first landing at the start of the game. It is a great representation and a challenge for the players to make a safe landing to colonize mars. Defying gravity with a spaceship requires the instincts of a true captain. A soft touch is necessary for not blowing up the ship or launching it into the space so try to land as smoothly as you can. As hard as it seems this classical game will make sure you have a great time.
