Very Realistic and enjoyable for all users. as the years went along and technology grew stronger and stronger...area 51 was no longer in need of use..due to this the underground labrotory/testing grounds were left on december 10th 2078. but the way the government left area 51 was undescribable...the government quickly locked down all compartments with all the workers along inside. until today february 9th 3009 area 51 was reopend and cleaned out. it is your job as a soldier/spec ops to clean out the HIVE so its called and kill all infected. Good luck soldier...let me know whats down there...
