In the film The Arrival, an alien race discovered earth, and attempted to modify its atmosphere to suit them, at humanity's expense. They failed - thanks to the work of Charlie Sheen's character Zane Ziminski.
Ten years later, the aliens are back, and have kidnapped you. You must escape without them knowing. Thus begins this adventure game, a non-canonical sequel to the original film. It takes in over 400 environments across the planet and its surrounding moons.
You have a first person view with complete freedom of movement. The puzzles have a science fiction theme, involving either object usage or looking for details. A hint system helps adventure game rookies to get used to the process of puzzle-solving. The game is non-linear and can come to several different endings.
