"Aliens: Colonial Marines has the uncanny ability to make you fear your surroundings. Vents, grates, loose ceiling panels, windows, doorways, cubby holes, weakened walls, storage containers and anywhere in shadow: these are your enemies. At any point in time in any given location, the scariest alien Hollywood ever produced could come bursting out from a dozen places around you and snack on your face (or your back) before you've even uttered a shocked expletive in reply. We're no strangers to things popping up in front of our crosshairs in shooters, but Colonial Marines' 360 degrees of terror is something new. It's also as constant an assault on the nerves as it is on health.", writes OfficialNintendoMagazine.
