The missions consist of you leading a few military men into battle. You get to use the right bumper to give out orders so that you can direct your teammates to go to various spots which will allow you to be more strategic. The problem though which hampers this is the fact that the A.I. is really poor. A lot of the times your teammates will simply charge into battle like blithering idiots, not waiting for orders and not thinking much about what is shooting at them.
Even beyond your own teammates’ A.I., the enemy A.I. is not any better. You will see your big boss battles be filled up with some truly stupid alien creatures. If these guys were smart enough to make it all the way to Earth, they sure as hell should be a lot smarter in combat-type situations since they must have known they would have to put up with some sort of fighting. Many of the boss battles have the bosses follow typical patterns with no variety which will truly bore you.
There is unfortunately not really a lot here to praise about Blacksite simply because it is just such a generic game.
Some of the cooler aspects of the game include the fact that you do get to drive around in some nifty military vehicles as well as use some high-tech weaponry. These wear off quickly though as they are all placed in the same game which by the time you get through the first few levels, you will be all done with.
One highlight of Blacksite: Area 51 is that visually it is not a bad looking game in any regard. There are a few problems with framerate here and there, especially later in the game, but for the most part it is a visually appealing release.
