Very mediocre gameplay, sub-par graphics.
Absolutely amazing story.
Think Apocalypse Now, but set in the present time (lots of story cues taken from Conrad's Heart of Darkness). I played through the game with the expectation of a craptacular shooter (and it was TBH), but the ending just blew me away. Definitely a good game for a cheap buy or rent. Not sure on the MP, I wouldn't want to deal with it considering the SP mechanics.
