The "Aliens" franchise has been scaring moviegoers since the late 1970s, with video game interpretations of the Xenomorphs beginning to show up in the early 1980s, on the Atari 2600. Numerous games over the years have pit humans against their biggest adversaries; some good and some not so good. The latest entry into the franchise, "Aliens: Infestation," manages to treat the source material with loving care, and bring the series to the Nintendo DS for the first time. Developed by WayForward Technologies and published by Sega, "Infestation" puts our species' biggest threat into the palm of your hand.
