i don't see a problem with IGN saying who's the final boss since it's pretty predictable but...
The game is insanely deep.

good lord,they just added some light rpg element! is that all it takes to make an insanely deep game?
anyway i reached chapter 4

NOOOOOOOOOOOOO THEY KILLED THE HORSE :'(
SADDEST MGS DEATH EVAH! :'(
good thing horses don't talk or we would have spent 5 minutes talking about carrots and hoofs and how they relate to peace

i don't understand how the ranking work
i've had an optional mission where i had to stop 40 guys from reaching a point,i camped the point and shot everyone down and got a C... why?
similiary i tried doing the first boss fight again,i did it in less than a minute but the game still scored me a B,what's the deal with it?
