Left 4 Dead

[ROCKFISH]

the survivors exhibit some of the worst AI i've ever seen, its only really worth playing with other people/friends.

its way better to actually pay for the game, though it sells soley on replay value, only 4 campaigns which take around an hour or less each, i'd say rent it and do a couple days of hardcore playing.

I honestly don't understand were you get the idea that the AI in L4D is bad...It's made by Turtle Rock Studies renowned for making some of the best AI in video games. I play this game quite extensively and I personally think your teammates work very well together for how much is going on. Be glad it wasn't some crappy EA team or something working on it or you wouldn't get through a campaign on easy

But seriously, this game is only truly enjoyable when your playing with your friends. Public servers just don't seem to cut it for me since its not guaranteed that everyone your going to be paired up with isn't a griefer or an asshole. But once you go through playing with some friends trying to survive a campaign on expert or go into some pubs you'd never play single player again.

Also, tip for killing the witch on any difficulty. Walk up to her with any shotgun and shoot her directly in the face point blank. If you do it just right its a one hit kill and you can get your "Crowned" achievement.
