I think it is the most realistic gametype in all of gaming. Why? because a bullet to the head actually kills you that's why.
"Using her tiny body as a shield, Alexis blocked six gunshots from hitting her mother. The bullets pierced her right eye, chin, cheek, chest and jaw."
A 7 year old girl can take bullets (note that plural) to the face and live. Your argument is invalid.
FFS, she took more shots than it takes to kill a shielded spartan.
The only thing unrealistic about this game is that these puny weaklings die in 5 shots instead of like 20.
