RE5 Shamelessly stole and butchered the L4D teamwork tactics.
I mean, resucitating your partner seems like reviving your partner, like in L4D.
When you get resuscitated, you have a tiny life bar that slowly ticks away unless you heal yourself. Sounds like the red bars in L4D.
Some enemies cannot be shaken off and require your partner to knock them off of you. Looks an awful lot like the hunter and smoker dangers in L4D.
'Course, this 5-hour gaming atrocity never would have happened if Capcom hadn't pussied out two years into development by having their arms twisted by black special interest groups, causing them to scrap the whole game concept and forcibly place a black, brain-dead partner in the game just to make sure there are never moments where Caucasian-Chris is alone, onscreen, shooting African zombies.
Hey, black people! I'm pissed off at you.
