I don't know. Seems kinda like WE'RE the assholes here in that demo. Took out a dude then started shooting. Maybe thems the breaks when the jungle is right outside the door (as in every MF-er in this room needs to die so too bad you decided to fight back), but really I was rooting for the guys trying to deal with Nathan Drake, home invader and his psychotic buddy.
EDIT - Heck, at least throw some kids or just women into the mix. Rough and tumble thugs that decide to come in ones and twos make the killing way too easy. And given it's a game, no amount of them will ever really be hard. Now having to tell Ellen Page she has to help you ice some little kids because they'll raise the alarm and your lives are the only ones that mattter...THAT is the hard choice in the post apocalypse.
