Game is great on PC.

@3RDRANGER The AI are actually very smart. They actually shoot at the enemies. Whereas on CoD they just sit in a corner and do nothing.

Hard mode is actually challenging compared to most games, but not impossible. The only thing I know that's more challenging would be World at Wars campaign on Veteran(mainly due to the fact that the enemies never stop throwing grenades at you).
