Here's an example of
the necessity of a DualShock 3: There's a cutscene after you defeat an enemy, and Snake reaches down to check their pulse to see if they're still alive.
You can feel their pulse through the controller. I was floored.
Act 2 Boss 'spoiler'It was Laughing Octopus. I didn't kill her, like i mentioned in a prior post I don't like the idea of killing women and I'm glad this game gives you the option of non-lethality. Perhaps you don't get the 'pulse feeling' thing if you do use lethal force, I might check that next time around. Also, if you defeat her without killing her, you get to use 'her face' on the face camo.
