Never played those games but if they show the players head to one side then an 'entity view' may be the way to go which can be a bit of a pain to script as all your required player animations that can be seen thru the entity view needs to be scripted in, not an easy task.
Without this view you will most likely get clipping issues where your player entity appears to be cut and consequently, 'seen thru' as thoug the model is unfinished.

Perhaps some one knows how to work a round this already, I dont know.

Other wise, a standard first person camera offset by the position of the camera on the shoulder will do the trick for you or any one who may be prepared to script this for you.

Just so you understand if no one takes up your request.
