old underrated n64 shooter. based off of goldeneye 007 but with major engine upgrades.
summary is you work against datadyne to uncover conspiracies and prevent total annihilation. rated an ign 9.0 to my memory. very obscure tho. check it out, look up perfect dark pc port and follow the instructions. it is incredibly fun on pc, arguably more so than the xbla or n64 versions because of its superior controls and good customizability. it was among the first of the "bleak" games but it is so unique and well done.
i recommend it but it is slower than most popular shooters due to its movement and aiming system. thus one would find solace in the characters, story and weapons rather than graphics and movement.
