Fallout 3 - Mothership Zeta Review @ IncGamers

6/10 is the score for Fallout 3's Mothership Zeta at IncGamers, with their review criticising the linear shooting:

The greatest element of Fallout 3 is the exploration and the freedom to come and go as you please when and where you want to. Mothership Zeta, however, plays out like Operation Anchorage and is all very linear. At one point in the game you can choose in which order to play a handful of the missions, but there really is no feeling of true exploration as you're herded down one corridor after another blasting aliens. Sure there are a number of areas in the ship to visit from the cargo room (amusingly decked out with mementos from Earth which the aliens have been collecting) to the machinery-heavy engine room, but it all starts to get too familiar too quickly. Whilst, as ever, the visuals are impressive, once you get past the initial awe and excitement of being beamed aboard an alien ship it all starts to wear a little thin.  There are a couple of standout moments, the finale being one and another about half way through when you get to don a space suit and carry out a space walk (Dead Space anyone?), but they are frustratingly few and far between.  Operation Anchorage was combat heavy and Mothership Zeta is no different. Bethesda has attempted to give you the option of taking a stealthy approach, as at the start of the game you team up with a child abductee, who scouts ahead (having climbed into the ships walls, Newt from Aliens anyone?), advising you of the locations of the aliens. However, this does not really work, as inevitably you will have to blast some of them at some point in order to progress. At this point, the others in the vicinity always come running.
