First time i bought it i didn`t really like it butafter playing it for hours and hours it really does grow on you honest
Weapons: Some of the weapons are impressive but not many of them,
Machine Gun: 8
Plasma Rifle: 8.5
Basically the others are boring.
Charcters: the characters are good especially the Soldier Cody Grayson who is a wisecrack king,
Somers however was a very good soldier until he was surrounded by aliens and became the Alien Leader.
Enemies: the enemies are cool the aliens are awesome especially the spore towers there huge and pretty easy to kill
the other area 51 is nothing compared to Blacksite since the storys better the weapons r greaty and the charcters are hilarious
Overall: pretty good i give it 6.0
